Need new MathCAD license and installation.

[MM_9393201]

I had Mathcad 6.0 for over a year and now suddenly it won't open. I tried to uninstall and reinstall, but now it will not install again.

Hi @MM_9393201,

Perform the below steps and then launch Mathcad as administrator

• Rename the file MathcadPrime.exe.Config to old_MathcadPrime.exe.Config  in the location "<C:\Program Data\PTC\Mathcad Prime>" 
• Rename the folder PTC to old_PTC in the location " C:\Users\%username%\Appdata\Local" 
• Clear temporary files on machine and launch Mathcad Prime

I hope this helps.

Thanks,

Vipul
