After Initial Splash for Mathcad, Software closes. Individualized on 1 computer and 1 user. Tried Uninstalling and reinstalling Mathcad to no changes. Can boot into Mathcad as an Administrator but not as a user. Saw a Windows Update for a previous version that fixed this issue before but not for Mathcad 8.0 Express and Windows 10.
Check out the solutions in the following articles:
