The typical workflow of a "new" Multikey fix in Windows 10/11 looks like the following:
This comprehensive technical guide explains why these licensing errors occur and provides legitimate, official troubleshooting steps to restore your SolidCAM workspace. Understanding SolidCAM Licensing and Multikey Drivers
: Virtual dongle technologies allow users to move their licenses to a virtual environment, reducing dependency on physical hardware. This approach can mitigate issues related to USB port compatibility and hardware failures.
Test signing mode was turned off, or a Windows update reset your boot configuration data.
: Look under "Universal Serial Bus controllers" for SafeNet USB SuperPro/UltraPro or Virtual USB Multikey . If it has a yellow warning triangle (Error 52), driver signing is likely still active.

The is a virtual USB driver that tricks SolidCAM into believing a physical USB protection dongle is plugged into the computer. It enables users to run the software without the hardware key.
Open the Command Prompt as an administrator and run bcdedit /set testsigning off (or on depending on your specific version's requirements) to allow the driver to function.
Recent Windows 10 and 11 updates (such as KB5004237) have increased security around driver signing, leading to several common issues for MultiKey users:
