I have an issue where a windows vista computer isn't running certain applications (iTunes, Quickbooks, Word). Internet Explorer works fine. Seemingly every program that needs authentication to run is throwing an error. I can't even run event viewer because of the error message above.
In adobe acrobat it says
[Window Title]
C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe
[Content]
C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe
The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more detail.
[OK]
In Microsoft Word it says
[Window Title]
C:\Program Files\Microsoft Office\Office12\WINWORD.EXE
[Content]
This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel.
[OK]
AVG says
[Window Title]
C:\Program Files\AVG\AVG9\avgui.exe
[Content]
C:\Program Files\AVG\AVG9\avgui.exe
The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more detail.
[OK]
Any ideas?
