ArcFix - Direct download

Very simple and lightweight program to fix Arc for Windows not being able to start on certain devices more than one time.

How to use

Open the ArcFix.exe (it will fix the issue until the session is closed)

If you want this program to launch automatically at startup instead of having to open it at every user session, open the Command Prompt at the ArcFix location (type cmd in the File Explorer address bar), then run the command ArcFix.exe startup on on it . It will automatically copy ArcFix to another location (%AppData%\ArcFix)

To kill the ArcFix.exe process, run taskkill /f /im ArcFix.exe in cmd

What it does

This program will simply automatically delete the %LocalAppData%\Packages\TheBrowserCompany.Arc_ttt1ap7aakyb4\LocalCache\Local\firestore\Arc\ folder when you close Arc.
