The Suprema.dll has not been properly registered on the local machine.
First check in C:\Program Files (x86)\Schneider Electric\Security Expert folder and confirm that the three files Suprema.dll, BS_SDK.dll, and BS_SDK_V2.dll are all present. If they are not you will need to copy them over from a working installation of Security Expert.
Now run the below commands via an Administrator authenticated command prompt session:
For 64-bit machines
- cd C:\Windows\SysWOW64
- regsvr32.exe “C:\Program Files (x86)\Schneider Electric\Security Expert\Suprema.dll”
For 32-bit machines
- regsvr32.exe “C:\Program Files\Schneider Electric\Security Expert\Suprema.dll”
You should get a pop-up saying the .dll was registered successfully.
Close and re-open the Security Expert client and re-test enrolling a users fingerprint.
