First launch of Win SDK Docs may cause Document Explorer error


This post applies to the RC release of the Windows SDK for Windows 7 and .NET Framework 3.5 SP1.

Issue: When launching Windows SDK Documentation for the first time, you may see the Microsoft Document Explorer error message: The Application Data folder for Microsoft Document Explorer could not be created.

Cause: On first launch, Document Explorer needs to create one or more files in the Application Data folder. The application needs to run in elevated mode in order to write to this directory.

Workaround: Run the application as an administrator. Under Start Menu, go to All Programs and expand Microsoft Windows SDK v7.0. Right-click on Windows SDK Documentation and select Run As Administrator. Provide administrator credentials, if required. This only has to be done on first launch. Subsequent use of Microsoft Document Explorer can be accomplished by a standard user.
