As a long time user of ATI AIW cards (sometimes known as serial-madness)
this is a well documented problem. Do a google search for "ati mmc
uninstaller" and you will find dozens of references.
All ATI drivers have to be removed before upgrading and ATI provide a
uninstall utility for this purpose. It should already be on your computer
and is called aticimun.exe
It should be in ...\program files\catalyst or ...\program files\ATI
Technologies\Uninstaller.
You do not say what ATI AIW card you are using but ATI puts a ceiling on
the
MMC version which can be used for any particular card. Make sure you have
the correct version.
Hi Rich,
I don't want to stray from the subject of "freeware" but I can pass on a
little lesson that will be useful to any one interested in uninstall
utilities.
I ran that ATI uninstall utility - over and over! But still it never got
rid of all the traces of Multimedia Center 8.5, and I was still unable to
install version 9.13. I did all the "manual" uninstall recommendations too,
no luck.
Finally, I hit upon a solution that work. I ran the original MMC 8.5
installation utility! It had three options - Modify (didn't work), Repair
(didn't work), and REMOVE. The Remove option did the trick. Then, and only
then, was I able to install MMC 9.13.
This made sense - the MMC 8.5 installation program knew where all the traces
of the program were put, because it put them there in the first place.
So, that's the moral of the story for ACF users - when trying to uninstall a
program, you just might check out whether the original installation file
came with a Remove option.
