During an upgrade from a recent nightly build to today's, I immediately get an error during the process before any dialogs occur. The error is 'Runtime error in install:
Cannot open file "C:\\DOCUME~\\..\\LOCALS~1\\Temp\\mia\\prereq.dfm". The system cannot find the file specified'
Before the runtime error I first saw a dialog box stating this: 'The process cannot access the file because another process has locked a portion of the file.'
It was after running the installer the 2nd time that the runtime error popup occurred.
The same build of the installer succeeds on many other machines, and even completes successfully on the same machine when tried again a bit later. We never saw anything like this with IA8; the issue only appeared after upgrading to IA9. It's been seen in both IA9.01 and IA9.06. Any idea what might cause this or suggestions on how to prevent it?
