MSI Error 1325. [username] is not a valid short file name

AutoCAD or other Autodesk product fails on installation or on the first run with the Error 1325.

This is a MSI installer error appearing on user accounts with names containing a dot (".") or with names longer than 11 characters. Users' login names probably have a period in their usernames - i.e.: "first.last".

What to do:

Install your CAD product in the Administrator account and then copy the Registry entries (HKEY_CURRENT_USER\Software\Autodesk) and the folders c:\Users\[username]\AppData\Local\Autodesk and c:\Users\[username]\AppData\Roaming\Autodesk.
