Issue: During installation you get error 1327, which references an invalid drive number.
Causes: The System Registry may be erroneously pointing to an invalid or temp drive.
Solution:
Back up your Windows Registry.
Open Windows Start menu, choose 'Run' (on Windows 10 press [WINDOWS + R]), type "regedit" and press [ENTER].
Navigate to the folder: HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\User Shell Folders
On the right search for entries that list the incorrect drive.
Modify the incorrect drive to the correct drive letter, i.e. C:\\.
