Unfortunately, last Windows secuirty updates, basically killed original OpenPort 2.0 Drivers because they are not WHQL signed.

  • If you have Windows 11 Pro or higher, You can disable signing check in Group Policy.

bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON


In both option, I suggest to install good quality Antivirus or use virtual machine.
