The problem may be that the Windows user environment is incorrectly mapping the registry entry Personal to a non-existing path.

In your Windows environment this is defined by the registry entry Personal in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

Make sure the value of the Personal entry points to valid folder.
