Problem opening the software

hey

I bought the software about two months ago
I learn and use it,
This morning I rebooted the computer and opened the software but it only opened the initial loading screen and then did not open the software,
I tried uninstalling the software and installing on a computer but it gave me the same problem.

I would like to know if you can help me open and use the software.

Thanks.

Hello VladimirN

Thank you for your response.

I tried to solve the problem using the tips you provided in the response.

1. . I couldn't find where to download the x32-Bit version of Mathcad Prime.

2. Cause: Bug with Windows security update KB4055002 for Microsoft.Net Framework 4.7.1 I tried uninstalling it, but the software still doesn't work.

When I run the setup file, it displays a green screen for 2 seconds, then closes the software. I have important material in the software that I urgently need to send.

I'm not very familiar with computer techniques.

Please help me find a way to successfully run the software again.

Thank you,

Have you tried the following steps:

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.
