Post script...
Today I decided to upgrade my desktop machine (home-built, pure MS retail Win7 Pro x64 installed from scratch... no pre-loaded vendor stuff like from Dell or ASUS) from 11.2 to 11.3.
Just two weeks ago I'd reinstalled both WinXP and Win7 (dual-boot) on this machine from scratch, because of some hardware changes. So this really was a brand new 11.2 environment, with 11.2 installed two weeks ago by simply running the downloaded ATI 11.2 "separates" (both DD and CCC) in a brand new freshly installed Win7 Pro x64 (early on in the install process). I prefer to install the two parts separately, rather than using the "complete suite" method.
Anyway, today I first took a system image just in case, and then started straightaway doing what was supposed to be possible... just run the new downloaded installer right over the existing installed environment.
So that's what I did. Just run the 11.3 version of the downloaded "separate" for DD... right on top of the existing installed 11.2
WORKED PERFECTLY!!!
Absolutely no problem, absolutely no need to install drivers manually, absolutely no need to first uninstall 11.2 before installing 11.3... nothing. Worked perfectly. And no nonsense messages about "your driver is already up to date".
Then I ran the 11.3 CCC "separate", again right on top of the currently installed 11.2 CCC. Once again... WORKED PERFECTLY!
I know... I know... this is exactly how it's supposed to work, so why am I claiming to be surprised.
Well, I'm not really surprised. I'm just still stumped as to why the other posters who have laptops and Mobility chips and vendor-installed OS's and ATI drivers, had so much trouble doing the same thing?
It would appear that if you just install normal full-retail software yourself (i.e. Win7, WinXP and ATI installers) there is no problem... although that really isn't a satisfying explantion at all. It's just hearsay numerology.
Anyway, I'm just adding my own very recent experience now, to the results list trying to update ATI drivers simply by running the downloaded installer files. WORKS PERFECTLY, right on top of existing installed ATI software... if your environment starts off "clean and pure" and without a vendor pre-installed OS.
Just saying...
