Hi! Alyx. Thanks for the details and for bringing this up, I'm here to help.
Recommended First Steps for You
Go to the actual install folder, confirm the .exe is there, and run it directly.
Check if it works when running as administrator.
If still broken, run it via Command Prompt to see if it complains about missing DLLs.
See if this helps. If you need further assistance, just let me know.
Best regards,
Kimberly
