Unable to open Mathcad Prime 11 Student. Older editions work but not able to open new files

Question

Im unable to open my Mathcad Prime 11.0.1.0 Student Edition. The app randomly crashed on me one day and when I tried opening it again, it does not do anything. No white screen, no error message, nothing happens. I've tried installing Mathcad Prime 10 but I am unable to use the files that I have in older editions.

I've tried multiple things:

- I've uninstalled and reinstalled.

- Deleted Files and tried running it.

- Tried running it using different compatibility modes.

- Tried running it as an administrator.

- Created Backup files.

- Nothing worked.

- Restarted computer

Again, I'm not sure how to fix this. If you could please assist me with this issue, I would greatly appreciate it. Thank you.

On your drive where windows is installed (usually C:), there's a folder

C:\ProgramData

(it's normally hidden, but you can type this in the top bar of windows explorer to go there.

Dig deeper and you will find:

C:\ProgramData\PTC\Mathcad Prime

In there is a file named:

MathcadPrime.exe.Config

a few kB in size. And or a file
MathcadPrime.V7.Config

The file(s) contain configuration info, but sometimes get(s) corrupted and prevents Prime from starting normally.

You can delete them and then retry to start Prime.

Prime needs the file(s) but will re-create any missing.

Hope this helps.

Success!
