While Setting up MS-Office 2010 You may get the following error

"There was a Problem setting up Microsoft Office Starter 2010.There was a problem setting up Microsoft Office. try Running Setup again. If the problem continues, contact Microsoft Product Support"

Workaround :

The issue is caused by incorrect value introduced into the registry at the following location:

[HKEY_USERS\S-1-5-18\ Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders]

"AppData"

This “AppData” location should be “%USERPROFILE%\AppData\Roaming. However on the machine where this bug repro’s this value is set to: “%APPDATA%”.

This creates a sort of infinite loop and end result is CSIDL_APPDATA, and %APPDATA% are no longer defined for system account and App-V connect fails.
