FB3 Driver blocked by Windows 11 Update 10.0.22621
Notice: 5/22/26
In recent Windows updates, starting around version 10.0.22621, Microsoft appears to have changed the architecture responsible for driver signature verification. As a result, the FB3 driver may be blocked by Windows after a certain period of time and/or after multiple system restarts.
We are currently working on a permanent solution to resolve this issue.
Update:
We now have a beta driver available that has been working successfully for all clients who have tested it so far.
Please download the driver using the link below:
You will need to manually update the driver. Instructions can be found here (click the image to enlarge):
We will post updates here as soon as they become available.
Our goal is to fully validate this new FB3 driver and include it in the next installer release for both software packages. Once the issue has been permanently resolved through this update, this notice will expire and be removed.
