Windows-11 Compatability

[GraemeT]

Hi all.
Has anyone else had compatability issues with running Cumulus MX on Windows-11?
Since build 3145, up to build 3257 I've been running the Windows compatability troubleshooter and that has sorted things out for MX to run happily. This morning I downloaded build 3263 and I find that Micro$oft has now killed off the troubleshooter, meaning I can't start the latest MX. I installed build 3257 about 3 or 4 weeks ago and it still runs ok on Windows-11 Pro 22H2 build 22621.2715.

Does anyone have any thoughts on this?

Not that it helps, but I haven't had any issues with CMX on Windows 11.

I installed CMX on it over two years ago, not needed to run the compatibility trouble shooter once. New version works fine too.

A bit more detail is required to troubleshoot - MXdiags files, screenshot of terminal window if that's how you start it, description of errors seen, and description of symptoms.

Sorry Freddie, no diag file is available, because MX 3263 literally won't start at all. As a result, it's not going to give me any information at all.
I don't believe this is a Cumulus issue. I believe it's something that's happened as a result of Windoze-11 updates and as most of us know, they can't easily be avoided or reversed..
I'm interested to hear from anyone else who's had this problem and if so, have they found a cure for it. So far, I'm at a loss as to what has happened.

One other detail, this was a clean install of Win-11 in March of this year on a pc that only runs Cumulus and web-related software. It's not an "upgrade install" from Win7 or 10.

MX is developed and debugged on Windows 11, it is 100% Windows 11 compatible. The compatibility settings are only needed for very old programs, or if something is amiss.

So as @freddie says we need more information. How are you starting MX (as a service, command line, script, launcher, ??)
Where is it installed, what is the exact error? Anything in the Windows error log?

As a note, the compatibility settings are still available on the files properties as they always were, but you have to set them manually rather than through the utility. I suspect MS withdrew the troubleshooter because there is so little need for it nowadays.

I've been launching Cumulus from a shortcut in the startup folder, as I always have in the past and when it would not start, there was no error at all, no command window, or messages.

Thanks Mark, for giving me the clue that led me to resolve this. I had managed to miss the manual compatability settings. When I went through it manually, Windows came back with a dialogue saying it has found issues with an incompatible program and 'fixed' them. I have no idea why my Windows-11 install no longer likes MX 'out of the box', but that seems to be the case. As I mentioned at the start, I believe this to be something to do with Windows updates and/or UAC. Also, I've never had trouble with compatability until I set up it on this pc.
Now it's starting correctly and doing exactly what it should, but I'm still at a loss as to why, so I'll be investigating further to find the cause.

Graeme, if you provide all the details of the install, it may help us suggest what is wrong.

What compatibility settings have been enabled?

[GraemeT]

CumulusMX.exe now starts and seems to be running correctly in Windows-8 compatability mode. That is all that Windows-11 will tell me about the settings.
Prior to compatability being set, there is nodiags file because literally, nothing happened when I tried to start Cumulus.

For what it's worth, here is CumulusMX diags file from after the compatability settings and the program test run, as well as Windows-11 information.
I hope this is useful.
