Problem
When you open Adobe Reader or a PDF you get the following error message:
Microsoft Visual C++ Runtime Library
“This application has requested the Runtime to terminate in an unusual way.
Please contact the application’s support team for more Information.”
This may also be followed by another message:
“Adobe Reader has stopped working”
Solution
Set the AppData variable to the correct value.
If that doesn’t work then try uninstalling and reinstalling Adobe Reader.
