Related issue: #1611 Somewhat related issues: #1006, #1191

Error:

App won't start with error code: 0xc000012f
mfc140u.dll Error

What I did:

sfc /scannow, DISM, regsvr32
reinstalled, rebooted
Installed .Net runtimes as well

Solutions:

1: Copy or replace the dll in %windir%\System32\. Get the 64-bit version (Architecture 64) of the dll from here:
```
https://www.dll-files.com/mfc140u.dll.html
```
The app should run with no errors after.

P.S. Problem prolly came from an error on Windows install. I had no issue on other Win11 install before.
