Invalid drive G:/

While trying to upgrade my iTunes 7.3 to 7.5 it can't be completed. Then I
get a windows dialog box with Invalid drive G:/

Why am I getting this message?

Is there an iTunes icon somewhere on the screen ? If so , right click
, exit , and then retry .

I would suspect your %TEMP% folder has some relic files in it. Start/Run, the
command:
cleanmgr

If no help, try to find out what the G: drive is. iPod? Flash drive?
