Mathcad won't open beyond splash screen after unrelated crash

[RC_7515533]

My computer crashed while using mathcad (unrelated crash to Mathcad). After restarting, Mathcad won't open beyond the splash screen. I have uninstalled and reinstalled the program, and keep getting the same results. Splash screen opens, closes, and then nothing else happens.

Tip - "Mathcad Prime does not launch after the initial splash on Windows OS": https://community.ptc.com/t5/Mathcad-Installation/Mathcad-Prime-does-not-launch-after-the-initial-splash-on/m-p/729884

Another one:

• 1. Create a backup (or just archive) of the config file (in this directory: C:\Users\CurrentUser\AppData\Local\PTC\).
• 2. Delete the current config file (in this directory: C:\Users\CurrentUser\AppData\Local\PTC\).
• 3. Run Mathcad Prime again.

Thank you.  The config file fixed it.
