Windows Update fails with code 606; "Error 1606.Could not access network location %APPDATA%\" RRS feed

  • Question

  • Windows Updates are failing on one of my users' computer. Update returns "Code 606  Windows Update encountered an unknown error."

    I enabled verbose logging per http://support.microsoft.com/kb/958052 . Initially, I couldn't find the logs. They are supposed to appear in C:\Documents and Settings\ {UserName} \Local Settings\Temp\. Instead, they appeared in C:\Windows\Temp. I checked, and %temp% resolves to C:\Documents and Settings\ {UserName} \Local Settings\Temp\.

    Inside the log file, I found "Error 1606.Could not access network location %APPDATA%\." %APPDATA% resolves to C:\Users\ {UserName} \AppData\Roaming.

    I searched for the error, and followed the instructions in http://support.microsoft.com/kb/886549. I wound up changing several values in HKLM\Software\Microsoft\Windows\Explorer\User Shell Folders. I found it notable that there is also a key with the name "{3D644C9B-1FB8-4f30-9B45-F670235F79C0}."

    I'm still getting the same error.

    User is running Windows Vista Business x64 SP2.
