Roblox says error code 403 occurs on PCs when the Roblox client launched from the website does not initialize correctly. If the error appears while starting an experience on Windows, reinstall Roblox first; if Roblox.com itself is denied in the browser, clear Roblox site data, update the browser, and test without extensions or a VPN.
Match the full message: 'Access to www.roblox.com has been denied' and 'You are not authorized to view this page.' Note whether it appears when the website launches the Roblox client or while Roblox.com is open in the browser; the next action is different.
Close Roblox. Search the taskbar for Control Panel, open Programs > Programs and Features, right-click Roblox, and select Uninstall or Uninstall/Change. Complete the prompts; the Roblox entry should disappear from the program list.

Windows 10 client: uninstall Roblox
Open Start > Settings > Apps > Apps & features, select Roblox, and select Uninstall. Complete the prompts. Skip this branch if the PC runs Windows 11.
4
Reinstall and test the client
Return to Roblox.com, sign in, and launch the same experience so Roblox installs a current client copy. When Roblox opens, verify that the experience reaches its loading screen without code 403.
5
Open local app data only if reinstalling failed
Uninstall Roblox again, press Windows+R, enter %localappdata%, and select OK. File Explorer should open the current Windows account's Local folder; stop if a different location opens.
6
Remove only Roblox's local folder
In the Local folder, select the folder named Roblox and delete only that folder. Do not delete the surrounding Local folder or unrelated app data. Restart Windows, reinstall from Roblox.com, and test the same experience again.
7
Browser case: isolate Roblox site access
If the 403 appears in Roblox.com itself, clear temporary files and cookies for Roblox in the browser, install the browser's current update, then reopen Roblox.com with extensions and VPN software disabled. Re-enable them one at a time after Roblox works to identify the specific conflict.
8
Compare one trusted second network
If the same 403 remains, connect the PC to a different trusted internet connection and retry once. If Roblox works there, the failure is on the usual network path; contact that internet provider rather than repeatedly deleting Roblox data.

If it does not work
If the error came from Roblox Studio, an API request, a school filter, or a third-party launcher, stop: Roblox's linked article does not establish that those 403 errors have the same cause.
If disabling browser extensions fixes Roblox.com, re-enable one extension at a time and remove only the extension that makes the 403 return.
If both a fresh client and a second trusted network fail, record the full message, Windows version, browser, timestamp, and completed steps for Roblox Support.
