  • Hi,

    This means that you either do not have the correct DLL or are missing a DLL (sysmain.dll).

    So we’d better copy this dll file from other same system version machine and paste it to this machine to replace sysmain.dll. The file location is C:\WINDOWS\system32\sysmain.dll.

    Then we could use command to registry this dll file.

  • Carl,

    I have similar issue. I checked the sysmain.dll and it is present in the system32 folder and properly registered.

    Any other ideas what can cause this issue?
