While installing device driver for my bluetooth adapter in my Windows 7 computer, I ran into an error (error 1327: Invalid H:\ drive). I have configure a folder called “My Documents” from the network drive H:\ as my primary document folder and I thought that might have caused this error with the installer. I deleted the configuration and disconnected the network drive (H:\) from my computer and executed the driver installer again. Still the same error.
After googling for a short while, I found the solution as follows.
- Open regedit.exe (type regedit.exe in Start > Run and hit enter)
- Find the key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders]
- Delete any values which start with the drive letter shown in the error message
