Catalyst fails to start due to MOM.Implementation error with .NET Framework

Windows did an updated to .NET framework 4 and after I restarted my computer everything looked fine at first. HDMI sound and screen resulotion were OK. A few seconds after my account logged in an error message appeared saying:

"Could not load file or assembly 'MOM.implementation' or one of its dependencies. The system cannot find the file specified"


The main issue now is that AMD Catalyst Control Center is not showing up. The drivers are installed correctly but CCC denies to start. 
I tried to :

Clean uninstalled catalyst.

Clean uninstalled .Net framework 4
Reinstalled .Net framework 4
Updated windows 
Reinstalled catalyst

But the problem was not solved. I tried installing .NET framework in different orders, older to newer and then install CCC but that did not work. Older versions of CCC has also been tested with no luck.

This thread has been tested with no luck either:
http://support.amd.com/us/kbarticles/Pages/26494-Radeon-MOM-CCC-implementation.aspx

My perfectly working hardware is rendered useless due to a software update/issue. 
And I feel helpless facing a problem for several days as if I was a computer engineer while I am just a humble customer.

Please help and thank you all in advance. 

System specs:
CPU: Intel i7-870
Motherboard: Gigabyte LGA1156 P55-UD3 
Graphic card: AMD Radeon HD6870 1GB
RAM: Corsair XMS3 8GB DDR3 
OS: Windows 7 64bit

Hi,

 

This error message is displayed when the AMD catalyst software is unable to find a file in the Microsoft .NET framework during its operation. The steps suggested in the AMD article you have mentioned usually resolves this issue. Since, you are still getting this error message, it is possible that some of the files were not deleted/ removed properly when AMD catalyst software was removed. I would suggest you to uninstall the AMD software and then remove all the associated files and then check. Refer to this article to remove the AMD software:

 

http://support.amd.com/us/kbarticles/Pages/GPU57RemoveOldGraphicsDrivers.aspx

 

Once you uninstall the AMD software, I would suggest you to make sure that all the AMD related files are removed. Try these steps:

 

a)      Make sure that the folder “ATI technologies” in the location C:\ program files (C:\ or the drive where Windows is installed) is empty.

b)      Make sure that the location “Documents and settings\User\app data\Local\ ATI\ACE is empty.

c)       Make sure that you remove any registry entries in these locations:

 

HKCU/Software/ATI/ACE

HKLM/Software/ATI/ACE

 

Note: Before performing any changes in the registry, it’s strongly recommended to make a backup of the registry. Refer to this article:

 

http://windows.microsoft.com/en-us/windows7/back-up-and-restore-frequently-asked-questions

 

You can also refer to the section “How to remove a Registry entry” in this article to find out how to remove any left out registry entries in the above mentioned registry locations:

 

http://support.microsoft.com/kb/136393/en-us

 

Once you have made sure that you have removed all the associated files, restart the computer and now perform a clean install of AMD catalyst software and then check if the issue persists. Let us know the results for further assistance.

 

Cheers,
Ben.

Hi Ben,

Thanks for your answer.
The method you have mentioned has been tested with no positive results. Everything associated with catalyst has been deleted. 

Drivers were sweeped.
Registery keys deleted.
ATI temporary folders and \User\app data\Local\ ATI\ACE were deleted. 
Windwos\assembly ACE,CCC,MOM and 
90ba9c70f846762e tokens were not found. 

Then we did a fresh install of catalyst 13.1 but the problem is still there. 

"Could not load file or assembly 'MOM.implementation' or one of its dependencies. The system cannot find the file specified"

Hi, did you have any luck with fixing the problem? I'm starting to think I have to format my drives and reinstall Windows, and I've also had no luck with the methods above about the .NET framework.

Thanks

hi

 

Ok , I've had this issue twice now, the first time was a few years back and was simple to sort out just by following AMD 's support page

http://support.amd.com/en-us/kb-articles/Pages/26494-Radeon-MOM-CCC-implementation.aspx

 

as mentioned above.

this time round was a nightmare or 6 to 8 hours going in circles, finally sorted it,

 

the fix for me.

 

follow the instructions on the above support page as every one usually does

: first make a system restore point.

: uninstall .net framework    (all of it, not just the recent updates)

: uninstall  your ati software  (everything)  you can use driver sweeper or follow amd guide http://support.amd.com/en-us/kb-articles/Pages/GPU57RemoveOldGraphicsDrivers.aspx

 

restart system and I use CCleaner to rid of any ATI leftovers. (warning this removes items from your registry so make sure you have made a restore point before starting any of this.)

 

now go into your registry (hit the start button and search for REGEDIT and run it)

you need to search for anything left from ati, I used these keywords (in regedit click on edit then find , put the word in there.)

ATI

CLI

CCC

MOM   (I think this was the big one)

and delete them (still make sure they are associated to Catalyst control centre, should say in description or right side of window )

 

restart system

then install .net framework, most recent being 4.5 (can use windows update or install file from http://www.microsoft.com/en-au/download/details.aspx?id=30653  )

restart system

then install most recent ati driver for your vid card, (not the beta)

http://support.amd.com/en-us/download

 restart system

and CCC should now run with no errors (hopefully)

hopefully this helps you if your problem still exists .

Hello,

It could be ever so good from the specialists to think about everyone in trying to bring more simple ways out to deal with such problems.

As far, as I am concerned, I now have to live with this error on my laptop since this morning, as I also have to live with a different error which appeared on my PC a few weeks ago.

Since I am not the only one, couldn't there be any patch made so that everything would be uninstalled and reinstalled in a proper and correct way without having to risk to get a total breakdown for those issues which are due to some sort of incompatibility?

We can just be feeling left out

Thanks

Joel

THIS WHOLE THING IS ANNOYING.  I had an update to Windows 10 and now I'm experiencing all kinds of problems that are mentioned above.  I am not a Tech person, I have no idea what anyone is talking about above as to fixing this, and frankly, my 2100.00 computer is now a piece of ****.

IS MICROSOFT GOING TO DO SOMETHING ABOUT THIS?  It was clearly a Microsoft 10 update that caused all this.

I am getting the same error message after the Windows 10 Update on Dec 25th, 2015. I notice the icon for the USB device eject function in the tray is no longer a green color.

I had this same pop up error message after the Win10 December 2015 update. Other than the pop up error my computer seemed to still be working fine.

When I looked for the Catalyst Control Center it appeared to have gone, although the program shortcut was still there.

On the Control Panel > Programs and Features the AMD Catalyst Control Center was still shown, along with the AMD Catalyst Install Manager.

I ran the repair option for the AMD Catalyst Install Manager. The Catalyst Control Center has also gone, whether I uninstalled this directly or it was removed by the repair operation I am not sure.

Looking at this link the Catalyst Control Center appears not to be needed any more:

Anyway, after a reboot I no longer get the pop up error message and the computer seeems to be working ok.
