Hi Abijit, I've been through this before and know how annoying it is. Ami gave a great breakdown already, but here are a few extra steps that helped in my case:
Method 1: Clear Temporary Files
- Press
Win + R, type%temp%, and hit Enter. - Press
Ctrl + Ato select all files, then delete them. - Skip any files that can't be deleted, that's normal.
Note: Check for conflicting software like Logitech G HUB, MSI Afterburner, RivaTuner Statistics Server (RTSS), overlays (e.g. Discord, GeForce Experience), or VPNs — these can interfere with Roblox’s launch or cause it to crash. Close or disable these apps before launching Roblox.
Method 2: Reinstall Visual C++ Redistributables
- Open Control Panel > Programs > Programs and Features.
- Look for entries like:
- Microsoft Visual C++ 2015–2022 Redistributable (x86/x64)
- Right-click and uninstall each one.
- Visit Microsoft’s official download page. under "Latest Microsoft Visual C++ Redistributable version". Download both:
- x64
- x86
- Once downloaded, run each installer. Choose Repair if already installed, or proceed with a fresh install.
- Please restart your PC afterward.
Method 3: Full Reformat (If nothing else works)
If the issue persists, you may need to reformat it as a final solution. Since none of the above steps resolve the issue, here's how to reformat Windows 11 on the same PC: (Please let me know if you’re using Windows 10 instead, and I can adjust the steps for that.)
- Make sure all important files are saved to an external drive or cloud storage.,
- Press Windows + I to open the Settings menu.,
- Go to System > Recovery.,
- Under Recovery options, click Reset PC.
- Select Remove everything (to completely reformat) or Keep my files (to keep personal files but reinstall Windows). For a full reformat, select Remove Everything.,
- Select either Cloud download or Local reinstall. Cloud download requires an internet connection and may provide the latest version.,
- Follow the on-screen instructions to confirm and start the reset. If you select Remove Everything, this will erase all data.,
- Once the reset is complete, Windows 11 will reinstall, and you will need to go through the initial setup process, like selecting your region and setting up your account, etc..
This will provide a fresh installation of Windows 11 and effectively reformat your PC. Feel free to let me know if you need further assistance.
