Mathcad 5.0.0.0 does not start (only background process) after Windows 10 1809 Update
The only thing that changed is the 1809 Update on my OS so I guess that's the cause but I don't know how to fix it.
Also Mathcad 4 does not work either.
Things I've done to try and fix:
- Delete and restore/ delete Mathcad related stuff in my AppData folder in Local and Roaming and Temp
- Reinstall countless times on different hard drives (both version 5 and 4)
- Turn off UAC/ Antivirus before installation and/or completely
- Checked to see if Mathcad window was just hidden, it wasn't
- Install all the vcredist, msxml and .net framwork stuff
This all applies to Mathcad 4 and 5 which worked flawlessly before the Windows 10 -1809 Update
I have the student version and refreshing license does not work either.
The logo appears, fades away and only the background process is left in task manager.
