Windows 7: 9.7 ATI drivers error

Anyone know what to do about this or why i'm getting it, In a pop up box when I try to open CCC

could not load file or assembly 'MOM.implemention, Version 2.0.3470.20910, Culture= neutral,PublicKey Token=90ba70f846762e' or one of its dependencies. The module was expected to contain an assemby manifest.

Anyone any ideas ?? can't get CCC to start just keep getting this message

This problem is historically associated with a bad .Net install.

Uninstall all ATI Catalyst software/drivers.
Do not Boot.
Re-install Catalyst.

Which version of Windows 7 are your running?

Did you upgrade the ATI drivers to 9.7 from a previous version?

If so, did you cleanup the previous version install using Driver Cleaner Pro and/or CCleaner?

If not that may be the problem and the solution. Uninstall ATI drivers, clean out old installations, re-install.

Driver Cleaner Professional download from Guru3D.com

CCleaner - Home

win 7 ver 7264 , upgrade, yes I made that mistake. no forgot trying it now.

done that reinstalled 9.7 an i'm now getting fail to install pop up when trying to install

I give up i'm gonna do a clean install of win 7, that should sort it I hope

Any more to the error message?

Edit: Sorry but I don't have a crossfire setup to compare against.

I've had a few installs of this new OS,im now running an x64 7600 RTM.
This is the 2nd install,the 1st one,i couldn't get the resolution i wanted 1024x768.
It's happened with a few installs i've done.
I've installed Windows 7 probably 7 or 8 times,this is only the 3rd time i've got 1024x768.
The last time was using a generic driver.
There's definitely an instability problem with custom graphics cards.
Sometimes with the generic driver it would boot up in the wrong resolution,and i'd have to correct it.

I'm getting 1080p no problem w/ my HD3870.
