'Could not load frontend.dll'

[godyun]

Hi all. I am new to the TS 2019. When I tried to log in the MMI, the following error message turned out.

---------------------------------------- Details: Could not load DLL or external library 'C:\Program Files\National Instruments\TestStand 2019\Components\Callbacks\FrontEnd\x64\frontend.dll'. Cannot load SxS version of cvirte.dll required by the DLL. Verify you have the SxS CVI run-time engine installed. Function LoadLibrary failed. Win32 Error Code = '1114' Error Message = 动态链接库(DLL)初始化例程失败。 ---------------------------------------- Error Code: -17004; Could not load DLL or library. ---------------------------------------- Location: Step 'Login' of sequence 'LoginLogout' in 'FrontEndCallbacks.Seq' ----------------------------------------

I have found the cvirte.dll and sxs.dll in system32 and sysWOW64, so this maybe caused by other errors.

Thanks for your help!

Best Regards

I would recommend running the version selector for TestStand.

Even if 2019 is the only version you have installed it would help to make sure all of the activex components and adapters are set correctly.
