Cannot Install ATI Multimedia Center

Did you ever figure out how to get around the previously installed version?
I am trying to overcome exactly what you described and am just as frustrated.
td

was to enter the registry, and do a search (Edit, Find) for instances of ATI, ATI Technologies, and MMC

However, for every one found, you have to make sure that the path on the right points directly to actual ATI directories, files, etc. because there will be other MMC listings that actually refer to MultiMedia Center files for Windows.

As I found the proper ones for ATI, I deleted the entire folder that was involved and not just the entry on the right hand side.

Be prepared.........there are MANY of them thoughout the registry, so plan on spending at least a couple of hours hunting them down in order to not only not miss any, but also to be able to take your time to make sure you aren't taking out the wrong entries.

Not a pleasant trip, believe me....but it worked. Before you start, also make sure you remove any entries that are in the MSCONFIG tabs, your Programs list, and in the C: folder list...and that you empty the recycle bin for any you manually delete. With XP, some of the C: folders will be by themselves, and others will be listed in the Documents and Settings for users listed. Also make sure you remove the ATI entry from Device Mgr so that only a generic video card is listed.....even if you do this in safemode. That will pretty much guarantee that you have a clean starting place for the new install.

I found a somewhat easiew way than Tommy (found it somewhere on the web, but deleted the link sorry!) First I uninstalled all the ATI software then deleted their folders (program files/ati mostly).
Then, I went to the registry (after setting a new restore point). Go to Hjey_Local_Machine. Expand Software, then ATI Technologies and delete all the keys EXCEPT Driver. Delete the ATI hotkey above it.
Remove your current Video driver and Ignore all the prompts to find a new one. Go back into Regedit and remove the Driver from the same Hkey_. . .
Reboot and again ignore all the prompst re New Hardware Found. When this is done, install the new MMC program (a driver is in it).
Hope this helps, and more importantly works for you!
