Installation Errors?
The rest of the post is dedicated to the variety of errors and workarounds when not following the above sequences. The length of this post should be incentive enough to stick to the script above.
If you've already run into problems, fear not. The rest of this post is dedicated to getting you up and running with Silverlight 2 Beta 2 and Visual Studio 2008 SP1 Beta.
Installer Contents
The "Microsoft Silverlight Tools Beta 2 for Visual Studio 2008" installer "silverlight_chainer.exe" contains the following installers:
| Silverlight.2.0_Developer.exe | Silverlight 2 Beta 2 |
| silverlight_sdk.msi | Silverlight 2 Beta 2 SDK |
| VS90-KB950630.msp | KB950630 for Visual Studio 2008 RTM |
| VS90SP1-KB950632.msp | KB950632 for Visual Studio 2008 SP1 Beta |
| VS_SilverlightTools_Beta2_Setup.exe | Silverlight Tools Beta 2 for Visual Studio 2008 |
You can extract the individual components using this command:
silverlight_chainer.exe /extract
The first thing you'll notice is that there are two KBs, KB950630 and KB950632.
- KB950630 is a patch for Visual Studio 2008 RTM
- KB950632 is a patch for Visual Studio 2008 SP1 Beta
The installer will apply the patch matching the installation of Visual Studio that you have. This is why you need to rerun the Silverlight Tools Beta 2 installer if installing Visual Studio 2008 SP1 Beta after installing Silverlight Tools Beta 2.
note: These KBs are ENU specific. The localized release of Silverlight Tools Beta 2 will have unique KB #.
The installation sequence used by "silverlight_chainer.exe" is:
- Uninstall Silverlight Tools Beta 1
- Uninstall KB949325
- Uninstall "Microsoft Blend for Silverlight Beta 1"
- Uninstall the Silverlight 2 Beta 1 SDK
- Install Silverlight.2.0_Developer.exe (Silverlight 2 Beta 2 Developer Runtime)
- Install either KB950630 or KB950632 depending on version of VS
- Install silverlight_sdk.msi (Silverlight 2 Beta 2 SDK)
- Install VS_SilverlightTools_Beta2_Setup.exe
Notice that the installer also uninstall's "Microsoft Blend for Silverlight Beta 1". You can get the updated version of Blend for Silverlight Beta 2 here.
SP1 Beta Installation Errors
Installing out of the recommended sequence above can result in installation errors or design time errors when using Visual Studio.
SP1 (Beta) Does not Apply
One of the more common error messages while installing VS SP1 is:
Microsoft Visual Studio 2008 SP1 (Beta) does not apply, or is blocked by another condition on your system. Please click the link below for more details.
This happens when installing "Microsoft Visual Studio 2008 Service Pack 1 Beta" before uninstalling "Microsoft Silverlight Tools Beta 1 for Visual Studio 2008"
Check out this post for more information: Error installing Visual Studio 2008 SP1 Beta and Silverlight Tools Beta 1
The solution is to uninstall Silverlight Tools Beta 1.
Important: You also need to manually uninstall KB949325 prior to installing Visual Studio 2008 SP1 Beta.
Failure to uninstall KB949325 is the source of most of the other errors and problems listed below.
Fatal Error during installation
During the installation of VS SP1 you may also come across an error such as:
The installation failed with the following message:
Fatal error during installation.
Click the Finish button to exit.
Check out this post for more information: KB944899 Should be Removed before Installing Visual Studio 2008 SP1
Error from silverlight_uninstallrtmpatches.exe

The above error has been reported and maybe related to installing on 64 bit Vista machines. This is the command that the silverlight_chainer.exe runs to remove KB949325. To get around this problem manually uninstall KB949325. The next time you run the the silverlight_chainer it will skip this step.
How to Validate SP1 is Installed Correctly
WARNING: Visual Studio 2008 SP1 Beta will report installation success even if KB949325 was not removed first. Unfortunately, failure to remove KB949325 will prevent some SP1 files from being updated.
This is why it's critically important to remove KB949325 before installing VS SP1.
One way to determine if KB949325 prevented SP1 from updating correctly is to check the version of Microsoft.VisualStudio.Web.Application.dll
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Microsoft.VisualStudio.Web.Application.dll
VS08 SP1 Version should be:
| Version | 9.0.30428.1 |
| Date modified | 4/29/2008 |
| Size | 468 KB |
If you have the following version it's from the Silverlight Tools Beta 1 release:
| Version | 9.0.21116.48 |
| Date modified | 2/23/2008 |
| Size | 492 KB |
This means that KB949325 was not removed and thus prevented SP1 from updating numerous files including Microsoft.VisualStudio.Web.Application.dll.
If you're in this state, read on carefully and see the "How to Recover" section.
Installing Silverlight Tools Beta 2
Unfortunately, unless you check files versions there is no obvious indicator that SP1 did not install all of it's files.
If you then installed "Microsoft Silverlight Tools Beta 2 for Visual Studio 2008" while Visual Studio is in this state with missed matched binaries you will get the following errors when running Visual Studio:
Creating new Silverlight projects:
Method 'SelectSilverlightProject' in type 'Microsoft.VisualStudio.Silverlight.SLPackage' from assembly 'Microsoft.VisualStudio.Silverlight, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' does not have an implementation.
Opening existing Silverlight projects:
Package Load Failure
Package 'Microsoft.VisualStudio.Silverlight.SLPackage, Microsoft.VisualStudio.Silverlight, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' has failed to load properly (GUID =
{CB22EEOE-4072-4AE7-96E2-90FCCF879544}). ...

Note that if you dismiss this dialog by selecting the "Yes" button then you'll need to run the following command later on after the installation has been fixed.
devenv /resetskippkgs
You'll also notice that in this scenario the version of Microsoft.VisualStudio.Web.Application.dll is still 9.0.21116.48.
Basically once KB949325 is installed it prevent subsequent patches from applying. This is why its critically important to uninstall the KB949325 before installing VS08 SP1 Beta.
As an aside if you install Silverlight Tools Beta 2 before SP1, it will remove KB949325. you'll just need to reinstall Silverlight Tools Beta 2.
How to Recover
Fortunately, all is not lost. If you do get into this state w/ miss matched binaries here is how you can recover.
The first thing you'll need to do is to uninstall the KBs installed by Silverlight Tools. To see these updates you'll need to run "Add/Remove Programs"
For Vista or newer:
- Open Uninstall a Program from the Control Panel
- Click 'View installed updates' in the task bar on the left
- Remove KB949325 (it will be listed under your version of VS2008)
- Remove KB950632 (it will be listed under your version of VS2008)

For pre-Vista systems:
- Open the Add/Remove Programs dialog from the Control Panel
- Click 'Show updates' at the top of the window
- Remove KB949325 (it will be listed under your version of VS)
- Remove KB950632 (it will be listed under your version of VS2008)
You may get this error "The patch is not applied to this product." when uninstalling KB949325.
Go ahead and disregard this error, we'll take care of it with the steps below.
Even after uninstalling both KB949325 and KB950632 you'll notice that the version of Microsoft.VisualStudio.Web.Application.dll is still 9.0.21116.48.
The next step will be to create a batch file containing the following commands:
rem Repair features Visual Studio SP1
rem ENU VSTS
msiexec /passive /i {80C06CCD-7D07-3DB6-86CD-B57B3F0614D8} ADDLOCAL=VWD_for_VS_Ent_5902_x86_enu /L*vx %TEMP%\dd_repair_VSTS.log
rem ENU VSTD
msiexec /passive /i {6721AC10-3743-38F1-B178-C0EC6C9A4108} ADDLOCAL=VWD_for_VS_Ent_5902_x86_enu /L*vx %TEMP%\dd_repair_VSTD.log
rem ENU PRO
msiexec /passive /i {D7DAD1E4-45F4-3B2B-899A-EA728167EC4F} ADDLOCAL=VWD_for_VS_Ent_5902_x86_enu /L*vx %TEMP%\dd_repair_PRO.log
rem ENU VSTA
msiexec /passive /i {8F10429A-DFF5-3B55-9306-0ADEB337CFD3} ADDLOCAL=VWD_for_VS_Ent_5902_x86_enu /L*vx %TEMP%\dd_repair_VSTA.log
rem ENU VSTT
msiexec /passive /i {23D0117E-F9A5-364E-A379-70EC2DE02B9F} ADDLOCAL=VWD_for_VS_Ent_5902_x86_enu /L*vx %TEMP%\dd_repair_VSTT.log
rem ENU VSDB
msiexec /passive /i {4298C783-524F-3C3E-9B11-36FA64604B2B} ADDLOCAL=VWD_for_VS_Ent_5902_x86_enu /L*vx %TEMP%\dd_repair_VSDB.log
rem ENU STD
msiexec /passive /i {F434F50E-7614-3EA8-9008-2FB866B697DA} ADDLOCAL=VWD_for_VS_Ent_5902_x86_enu /L*vx %TEMP%\dd_repair_STD.log
Run the batch file you created with the above commands. This will put VS back into a recoverable state. Note that the KB949325 will still be listed in Add & Remove Programs. Unfortunately it'll continue to show up even though it's been uninstalled.
Now re-install "Microsoft Silverlight Tools Beta 2 for Visual Studio 2008". You can also do this by running Silverlight_chainer.exe again.
Confirm that KB950632 is shown when viewing installed updates in Add/Remove Programs.
Confirm that the new Beta 2 version of Microsoft.VisualStudio.Web.Application.dll is:
| Version | 9.0.30428.9 |
| Date modified | 6/3/2008 |
| Size | 512 KB |
Other Errors:
“Object reference not set to an instance of an object” when adding a WCF service" - Crash on Exit
Tim Anderson has found a work around for the following problem and posted a solution here
- Error “Object reference not set to an instance of an object” when adding a WCF service
- Silverlight app cannot see WCF services in same solution
- Error “Unable to find ‘DynamicTypeService’” when clicking the Advanced button in the Add Service Reference dialog.
- Visual Studio crashing on exit
We're almost done!
If you now get an error creating or opening Silverlight projects:
The project type is not supported by this installation

You'll need to run the following command:
devenv /resetskippkgs
Finally, if no controls are showing up on the toolbox when editing Silverlight XAML pages then you'll need to:
delete %LOCALAPPDATA%\Microsoft\VisualStudio\9.0\toolbox*.*
At this point you should be up and running with Visual Studio 2008 SP1 Beta and Silverlight Tools Beta 2.
Where to go for Installation Help?

As many of you know Silverlight 2 Beta 1 was release today at MIX08. What an awesome day. The new applications under development based on Silverlight 2 are truly incredible! Check out http://www.microsoft.com/silverlight/
To get started with Silverlight 2 you can download "Silverlight Tools Beta 1 for Visual Studio 2008" here.
The Silverlight Tools installer will install everything needed to start working with Silverlight 2 in Visual Studio 2008.
It installs the following:
- Silverlight 2 Beta 1
- Silverlight 2 SDK Beta 1
- KB949325 for Visual Studio 2008
- Silverlight Tools Beta 1 for Visual Studio 2008
Even if you've previously installed Silverlight 1.0 or Silverlight 2 Beta 1 the installer will proceed and install the additional components.
That's it! You're now ready to start creating rich Internet applications with Silverlight 2 and Visual Studio 2008.
While the installation is that simple in most cases, there have been some installation issues reported. I've listed below the issues and solutions I've run into so far. I'll update this post if new issues are reported.
Installation Error
If you do run into an installation error, it's most like due to a previous installation of Silverlight 1.1 Alpha or any of the Silverlight SDKs, including the Silverlight 2 Beta 1 SDK. You must uninstall all these components before installing Silverlight Tools Beta1 for VS08. If you don't uninstall these products first you'll get this error dialog from the installer.
If you see this dialog, be sure to uninstall all the dependent components and restart the installer.
Can't Find KB949325 to Uninstall?
If you ever need to uninstall KB949325, you can do this through Add and Remove Programs. However it does not show up by default in Add and Remove Programs.
Instead you need to select "View Installed Updates"
Now you'll see all the updates and patches installed to applications on your computers. Scroll down and you'll find KB949325. It will be listed as:
It should not come as a surprise that if you uninstall KB949325, you will not be able to use Silverlight projects in Visual Studio. Only uninstall KB949325 if you're planning on returning VS08 to its RTM condition or if you're attempting to reinstall Silverlight Tools.
Prompt for installation source media
In some cases you may get a prompted for the installation CD-ROM for Visual Studio 2008.

Heath Stewart has an excellent blog post on some of the issues users are encountering when installing patches for Visual Studio 2008. You can read his entire post here. Heath has a new post specific to this prompt when installing Silverlight Tools here.
One of the scenarios causing this to happen with the Silverlight Tools installer is when Visual C++ is not installed. The other component that will cause this to happen is if you don't have the "Microsoft Visual Studio Web Authoring Component".
You can manually get around this. First you'll need to extract the individual installers from the Silverlight Tools Beta 1 for VS08 chained installer. To do this download and save the Silverlight Tools chained installer from here and save it locally.
To extract the individual installers run this command: silverlight_chainer.exe /extract
This will extract the following installers, along with other support files.
- Silverlight.2.0.exe
- VS90-KB949325.msp
- silverlight_sdk.msi
- VS_SilverlightTools_Beta1_Setup.exe
It critical that you install these components in the order listed above. (Silverlight 2, KB949325, SDK, Tools) To install KB949325 w/o being prompted for media run this command:
msiexec /p VS90-KB949325.msp /L*vx VS90-KB949325.log REINSTALL=ALL
Note: this command will require administrative rights and it does not add the KB to Add/Remove Programs.
To list these Silverlight tools in Visual Studio's Help->About dialog and to be able to uninstall these tools from Add/Remove Programs (ARP), install the patch again using the following command:
msiexec /p VS90-KB949325.msp /L*vx VS90-KB949325-2.log ADDLOCAL=KB947520,KB949325
Finally run the VS_SilverlightTools_Beta1_Setup.exe installer to complete the Silverlight Tools installation.
The project type is not supported by this installation
Even when installed successfully, some users have seen this error:
This is happening for users who have installed previous builds of Silverlight Tools and for one reason or another the Silverlight package for Visual Studio has been disabled. You can re-enable the Silverlight package by running the following command.
devenv.exe /resetskippkgs
The ASP.NET Silverlight controls show appear in the Toolbox for .aspx pages
This happens if the Silverlight SDK is installed before KB949325. As listed above the install order is important. To fix this uninstall the Silverlight SDK and re-install it.
Help Files don't show up in Visual Studio
To integrate the VS help files included in the Silverlight 2 SDK follow the instructions in this readme.txt installed with the SDK.
[Program Files]\Microsoft SDKs\Silverlight\v2.0\Documentation\VS-Help\Readme.txt
The installer is hung?
At the end of the installation process the installer appears to be hung.
The installer can take up to 10 minutes at the end of the installation process. What's going on? The last thing the installer does is merge the help dictionaries. If you've installed the help files for VS locally this can take some time. Don't kill the process, it's not hung.
Where to go for Installation Help?
Be sure to check out the Silverlight 2 Beta 1 readme for known issues.
