Chm files and 404 Errors

I must say I was amazed that when I downloaded the latest Windows SharePoint Services 2.0 Administrators Guide I only got 404 errors on every page in the contents. I downloaded the file another time, to no avail. I gave up and thought: well, the file must be corrupted. But no: this is one more step by Microsoft to provide us ultimate security!

I stumbled across this blog entry by Mark Kruger that provided the solution:

1. Right-click the CHM file, and then click Properties.
2. Click Unblock.
3. Double-click the .chm file to open the file.



  • Same happens when you try to open a .chm file from a remote location on a LAN for instance. In order to have it working, copy the .chm file to your local system and open it...

  • I encountered this after i downloaded the VSTS install guide. Luckily the download page had this info in the bottom, thats how i figured this out. I was kind of annoyed at first when i couldn't read the help file, went back read through the whole download page and there it was in the bottom.
