'...is not a valid win32 application'
'The set up files are corrupted. Please obtain a new copy of the software.'
Sidney1st is asking him to redownload the programs again due to this message the OP stated he received in the 1st post. I agree that this is also the first thing he needs to do.
I also just ran across this statement from Microsoft regarding the "not a valid Win32 application" message:
Microsoft is aware of this issue and is working on a fix
. As several people have observed, this is konwn to affect Excel 2007, Access 2007, Snipping Tool, and Windows Media Player on Vista SP1. The fix
is to either exit as many apps as possible that you are running (e.g. Outlook), and then load the app (and then you can reload the apps you had running), or a logoff/logon will clear it up for a while (days/weeks). The error messages are confusing, but the problem is neither an invalid application
file nor insufficient system resources. It only affects certain applications, and typically only after the user has been logged in for an extended period of time.
I read from many users that this error also went away after rebooting and running the installation again.
