Issue Details

When I open the MPManager, it showed Error Message "MPManager has stopped working".
I tried to uninstall/reinstall MPManager in several times, but still happened problem.


The Runtime errors such as "CLR20R3 error" can occur for a variety of reasons,
  • This error is caused by an automatic shutdown when an unhandled exception occurs.
  • Another program deliberately or accidentally deleted MPManager-related files.

Here are some steps to solve this issue.
  1. Delete all of the contents of the following folder: C:\Users[USER]\AppData\Local\Micropross
  2. Check whether problem solved
  3. Still have problem
  4. Reinstall MPManager (available in the download center)
  5. Re-install the test suite
  6. Update latest .NET Framework
