Panasonic KX-TDA100 (U.S.) - Error E000012

[selcom]

Can somebody help me to troubleshoot this issue?

*** E000012
*** The program is not installed correctly

I tried with the PBX Unified Maintenance Console 7.8.1.1 R14 and R17 and I get the same issue. My PC is a Dell Optiplex 9020 with Windows 10. Communication by USB cable.
