Window shows Nothing

Hey I have the problem that I installed the we mod exe on the PC but it dont show anything in the Window can someone help ?

Exit app completely (from taskbar) then open again.
If this wont help reinstall the app.
If this wont help either its most likely antivirus interference.

What antivirus do you use ? Its most likely your AV blocking the wemod exe

i did every steps and i use windows defender and it s off
