ATI MOM.Implementation Error on Windows XP Professional X64

[Guest]

Dear,

I have a problem when I installed unistalled graphics drivers and then I
installed back the drivers on Windows XP Professional X64 version. I have ATI
graphics card X1950 Pro 256mb. I installed the Ati Catalyst 7.1 drivers and I
also tried the new Catalyst 7.2 drivers.

A now the problem - Error -> every time when the Windows XP Pro X64 version
start I get the error message in an Ati window that said -> Could not load
file or assembly "MOM.Implementation" or one of its dependencies. The system
cannot find the file specified.

What can I do to stop or repair the error. The restor point to older dates
does not resolve this problem.

Thank you.

Kind regards.

Hi,
I found a similar issue after upgrading to Windows 7 x64 from Vista x64.
I believe that the issue does not lie with the version of the OS but in the
prerequisites that the Catalyst needs to successfully function.
I found that there appeared to be an issue with .Net3.5SP1 and the Catalyst
install after the upgrade which, generated a similar MOM.Imlementation error
that stopped the Catalyst Control Center from loading.
To correct this I removed .Net3.5SP1 (Unchecked the package from the Turn
Windows Features On or Off - in windows 7 and Vista) and installed a fresh
copy of the Catalyst Package including the C++Redistributable which, is
included in the Catalyst Package, with ought a problem. Windows 7, I believe
is built on .Net2.0 and the Catalyst package requires these components to be
in good health.
I hope that this is of some assistance to anyone out there experiencing
similar issues.

This is a real bear.
I have an ATI Radeon HD4850 card that was originally installed on my
Dell XPS Windows Vista Home Premium 64 with an i7-920 processor.

If you are here, you already are looking for the problem. My situation
is the same. Major problems with the 9.6 suite. I downloaded the 9.6
suite update, installed it, got errors near the end where the catalyst
control center (CCC) is being installed, along with the
MOM.Implementation or other similar pop-ups containing specific version
codes like version=2.0.3455 .

I tried a number of different things after reading forums, then decided
to sleep on it since none of it was working properly. This morning I
tried a new approach, combining a bunch of things I had already tried.
This is the sequence that worked for me.

1. Ran UNinstall using the ATI 9.6 full suite software.
2. Ran CCleaner to uninstall the remaining ATI program (the suite
installer).
3. Ran 3DGuru Driver Sweeper to look for and uninstall any ATI drivers
(it found many files).
4. Looked for ATI folders in User Docs, Program Files, and Program
Files (x86). Found files in all locations, and I deleted the files and
folders within these ATI folders.
5. Restarted computer. (the restart was very slow, and when you come
back up, your screen will be low res). No MOM.Implementation error
popup.
6. Ran the ATI 9.5 suite (NOT 9.6)--selecting everything, including the
CCC. At the end, there were errors indicating the drivers did not
install properly (!).
7. Ran the ATI 9.6 DRIVER INSTALL ONLY (not the 9.5!, and NOT the
entire suite).
8. Let the computer restart, shutdown is very slow and drawn-out.
Walk away for a while. Once restarted, no MOM.Implement error comes up.
9. Checked on the advanced monitor settings and had access to the ATI
CCC (which I did not have before).

In summary.
Delete everything ATI using various methods.
Restart.
Run ATI 9.5 to install the suite - drivers+CCC.
Then run ATI 9.6 driver only.
I think I am probably running ATI CCC 9.5, and ATI 9.6 video card
drivers at this point. It is hard to tell. There is no doubt that
something is not right in the 9.6 CCC install, but the 9.6 video drivers
seem fine.
