I have my personal profile's Documents folder redirected to a network drive H:\ . This was done by right clicking on Documents, Properties, choosing Location, and selecting H:\ .
I have a problem where some (I am not sure whether it is all) MSI installers will fail with an "Error 1327 Invalid Drive H:\" when I attempt to install them.
As a workaround, I can edit the registry at
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\
and set the registry key "Personal" temporarily back to "%USERPROFILE%\Documents", do the install, and then change it back. I don't know why this needs to be done though, as nothing is actually installed into that directory.
Does anyone have a more elegant solution?
