NextPVR client not compatible with Windows Server 2022?

[itm2]

I've installed NextPVR (v6.1.1.221106) on a Windows Server 2022 machine. The server installed OK, but when I try to run the NextPVR Client I get the error below. Is the NPVR client incompatible with Windows Server 2022? 

Code:

System.NullReferenceException: Object reference not set to an instance of an object.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

You need full DirectX and if it is not installed you need the -nogl parameter

Note: For some tuner devices you would need to manually hack in the BDA drivers, they are not included in Windows Server.

dxdiag tells me that I have DirectX 12 installed. I have now tried grabbing BDA drivers from a Windows 7 machine (with limited success - some files copied, some didn't). The NPVR client still gives the same error, but the -nogl option works

[mvallevand]

It is more than having dx12, something is missing in DirectX, and it is not clear what it is. You aren't the only one posting this.

I don't understand your last sentence. If you are seeing the error in the logs when it works, post the zipped logs.

[itm2]

Sorry I wasn't clear - if I run the NextPVR client from the Start menu it fails with the same error is before. However if I run it from the command line, with the -nogl parameter, it works

[mvallevand]

Logically you would need to add that parameter to the Start Menu shortcut and any other shortcuts you make.
