Run the MT-CP-8090.exe (Credential provider) installer, but do not follow the wizard, keep it on the first screen. This will create a temporary installer in the same directory where the MT-CP-8090.exe is, for instance:
Copy and rename this file, for example, MT-CP-8090_offline.exe
Close the MT-CP-8090 installation wizard. This will remove the temporary installer extracted from the MT-CP-8090 but your copy will remain.
The copy you got can be used with command-line arguments. Use /? for help:
.\MT-CP-8090_offline.exe /?
For a silent uninstallation:
MT-CP-8090_offline.exe /uninstall /quiet
Even though the installation can be done silently, you still have to go through the API setup manually afterward.
