Roblox Won't Start/Download


Thread Starter
Aug 1, 2020
It worked fine for 3 years, but today when I tried playing it said updating before giving me an error message saying the following:


An error occurred while starting Roblox

Details: Unable to open file for writing:
C:Users\Sam\AppData\Local\Roblox\Downloads\.part: The process cannot access the file because it is being used by another process.

I've tried multiple times to reinstall it and keep getting the same error, I even tried a system restore point from 2 weeks ago and it still wasn't working.

Is ROBLOX open in Task Manager (before installing [if so close it])? Can u manually delete the file in Windows Explorer?
