The "Sentinel Emulator 2007" driver predates this requirement and is unsigned. When you try to start its service, Windows blocks it, stopping the emulator from working.

Create a new virtual machine and install a 32-bit operating system, such as or a 32-bit version of Windows 7 .

Once the driver is signed, the emulator should load without error each time your PC starts, as long as Test Mode remains active.

Updated drivers are fully signed and 64-bit compliant. Visit the official Thales Customer Support Portal.
