This issue with Windows 11 upgrade does not seem to be an issue with Atlas’s end-user license holders (i.e. with users who bought the license directly from our website or one of our distributors), but with OEM license holders.

Thus, if you did get your cFosSpeed Version as OEM via ASUS, ASRock, MSI or Gigabyte, updates and support for such versions are only available via our OEM Partner.

Our suggestion is to totally remove the service from your PC and retry the installation.

However, in order to get the OEM version of the software again, you will need to contact the OEM, or download and buy a licence from our website.
