Visual Studio 2008 Web Test Not Recording on 64-bit Windows 7

I was about to record a web test in Visual Studio 2008 Team System today, and the recorder refused to record anything. And the Recorder “bar” in IE 8 was not showing. After some digging around, the issue was fixed by deleting a few registry keys. Found it on Michael Taute's Blog : Diagnosing and fixing Web Test recorder bar issues.

Quote from his blog page:

Vista caches the list of explorer bars you have available and the recorder bar was not included in your list. The fix is to force Windows to rebuild that cache. To do this, first make sure you have all Internet Explorer instances shut down, then open the 32 bit registry editor and delete the following keys:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Discardable\PostSetup\Component Categories\{00021493-0000-0000-C000-000000000046}
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Discardable\PostSetup\Component Categories\{00021494-0000-0000-C000-000000000046}

[Note: by default, the 32 bit registry editor is located in %WINDIR%\SysWow64\RegEdt32.exe]

The next time you boot Internet Explorer, your explorer bar cache will be rebuilt and the recorder bar should be available.
