Can't start CMO--error, please help me

[BigBog]

Hi Tech Support for CMO,

21 year Matrix fan and long time player of CMO, CMANO, and before that Harpoon--love them--my fav sim/games of many that I've played.

I've recently went to play a couple scenarios of CMO but fund that I keep getting this error. I believe that I had a Windows 10 update that went a day or so before I first ran into the error. I can't figure this out--and have spent a few hours trying. Error checked my SSD, validated the program files on Steam (none missing), checked and reinstalled my .NET stuff, to no joy.

Interestingly, if I switch to the 32-bit legacy game version, the game runs, but the default public version and the public beta multi don't. Prior to the current issue, I could run both the default and multi versions fine--just a few days later, boom---won't go-?

I am attaching the error log and also screen shot of the error message.

Let me know if you need anything else to help me diagnose why I now have this error--

Thank you,
Rob Miceli

That's new! Never seen this one before, ever....

[Dimitris]

From initial investigation, it seems likely that your .NET Framework installation has been corrupted (at the very least, an abnormal version of System.Data.dll has been introduced). Please try to repair your .NET installation (see here: https://learn.microsoft.com/en-us/dotne ... all/repair ), and give it another try.

Thanks Dimitris,

I tried the fixing of the .NET using the repair tool from the link you provided.
It said that I already had the latest version of the .NET 4.8 or later...

So, no joy---
Very strange that the Legacy version of CMO runs, but not 1900.23--?
I have no other problems from other programs that use .NET architecture. And I didn't have any problem before the latest CMO version. Weird.
Let me know if you've got any other insights to this issue...and I'll keep trying here to figure it out.

Best,
Rob

If your case is also related with 3rd party software that interferes with CMO loading, take a look at this list and try to disable it, restart and try CMO again.

The table is AI generated and of course not comprehensive, so you may also search in the task manager, startup tab when you just start the computer.

Hi Nikel,
I tried shutting down everything that is on that list that I had running--no joy.

I also removed and reinstalled .NET 4.8 and was hopeful---no fix.

Thank you,
Rob

What is started up in your computer from that list?

[Dimitris]

Let's go through the standard checklist:

* Is the OS fully updated? Graphics drivers updated? Direct-X 11 installed?
* If running on a laptop with a discrete GPU: Is Command using the iGPU or the dGPU? (see here: https://forums.matrixgames.com/viewtopic.php?t=409198 )
* Is Command running as admin? (ie. prompting you "are you sure you want to run this program" when you launch it)
* (Steam only) Are Steam overlays disabled for Command?
* (Steam only) Is Direct-Write disabled on the Steam client?
* If running Discord: Are game overlays disabled?
* Are all other applications (and especially hardware-helper apps like RivaTuner, Nahimic, Nvidia Share, MSI Afterburner etc.) shut down?
* Are you using a high-DPI desktop? (ie. font size >100%)
* Are you using Norton antivirus? (This POS is very frequently silently blocking file updates)
* Can we see your DxDiag file?

Hello Dimitris,
Here are my answers and the DxDiag file attached:

* Is the OS fully updated? Graphics drivers updated? Direct-X 11 installed?
Yes, OS latest updates, extended service for Win 10. Have latest nVidia drivers. Have DirectX 12 installed

* If running on a laptop with a discrete GPU: Is Command using the iGPU or the dGPU? (see here: https://forums.matrixgames.com/viewtopic.php?t=409198 )
Not laptop.

* Is Command running as admin? (ie. prompting you "are you sure you want to run this program" when you launch it)
I have tried to run it as Administrator from the .exe file, without the launcher. No joy.

* (Steam only) Are Steam overlays disabled for Command? YES

* (Steam only) Is Direct-Write disabled on the Steam client?
The legacy "Enable DirectWrite" checkbox has been removed from modern Steam client interface settings, and DirectWrite is now handled automatically by Steam's embedded browser framework (CEF) on Windows

* If running Discord: Are game overlays disabled? Not running Discord
* Are all other applications (and especially hardware-helper apps like RivaTuner, Nahimic, Nvidia Share, MSI Afterburner etc.) shut down? YES
* Are you using a high-DPI desktop? (ie. font size >100%) NO
* Are you using Norton antivirus? (This POS is very frequently silently blocking file updates) NO, It sucks, I agree
* Can we see your DxDiag file? Attached

[Dimitris]

Thanks, the DxDiag file in particular is helpful.

This caught my attention:

Event Name: WindowsWcpOtherFailure3

P1: 10.0.19041.7789:1
P2: wcp\componentstore\csd_core.cpp
P3: CCSDirect::GetComponentManifest
P4: 584
P5: c015001a

This is related to Windows Component-Based Servicing (CBS), which manages Windows system components. The component store is involved in maintaining Windows components, including .NET Framework components.

Can you please run these in an admin-elevated command prompt:

DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Then reboot and retry.

[BigBog]

Hi Dimitris,
I tried the recommended scan and fix--
I really thought we had it nailed, because it found a bad file when scanned and it said it was "repairable".
Did the repair and it spent a long time at 62% repairing.
Rebooted and ran CMO---same error--crap!

One thing I puzzled about: how come the 32-bitlegacy version from 2023 works and this new version won't?
Also, I had the multiplayer version running prior to this version 1900.23. So, very strange that this new one won't work.

Appreciate the help--hopeful we can find problem soon. But I am playing CMANO in the interim!

V/r,
BigBog
