Every now and then (see examples when below), I'm getting
a Windows Installer dialog error message as follows:
"The feature you are trying to use is on a CD ROM or other
removable disk that is not available.
Insert the Microsoft Office XP Professional disk and Click
OK."
There's a Browse button.
As far as I know, there's never been Office XP
Professional installed on my PC.
It's looking for a file PRORET.MSI.
Examples of when this happens are when I right click on
Desktop icon or when I right click on a filename when in a
File | Open dialog.
Any ideas what do, other than trying to get hold of an
Office XP Professional disk? Any ideas why this is
happening?
