The linux 2.6 overrides two of the main ATI drivers.
(libaticalcl.so libaticalrt.so) and the README.txt tells you to install any 12.1 driver AFTER the 2.6 SDK (since it overwrites those 2 files and they obviously must be pre 12.1)
So there may well be a similar issue on windows - but of course I don't know since I don't mine on windows.

So you're saying install 2.6 first, then a pre-12.1 driver? or 2.6 and THEN 12.1? I'm noticing that it is 'overwriting' something because it actually deletes the 2.1 kernel but doesn't replace it.

I would do a manual clean of all ATI files, and then manually install exactly what you want.
1. In control panel -> programs and features, uninstall all AMD APP SDK/ATI Stream SDK items
2. In control panel -> programs and features, use the ATI Catalyst Install Manager and pick uninstall ALL ATI software.
3. Reboot into safe mode (beat on F8 when the computer restarts), and remove these files manually:
- in \Program Files & \Program Files (x86)\: ATI, AMD APP, ATI Technologies directories
- \AMD and \ATI directories
4. In \Windows\System32 and \Windows\SysWOW64, delete these driver files left behind (they will all have the same date):
amdocl.dll
opencl.dll
amdpcom32.dll
atimpc32.dll
atiu9pag.dll
atiuxpag.dll
atigktxx.dll
atiglpxx.dll
atiadlxx.dll
atiumdva.cap
atiumdva.dll
aticaldd.dll
atiumdag.dll
atiumdmv.dll
aticalcl.dll
aticalrt.dll
atioglxx.dll
atidxx32.dll
ati2edxx.dll
atimuixx.dll
atipdlxx.dll
atitmmxx.dll
atiesrxx.exe
atieclxx.exe
ATIDEMGX.dll
aticfx32.dll
atiapfxx.exe
atiapfxx.blb

5. In \windows\inf, open each oem??.inf files with notepad, any that are clearly for ATI Display, delete the inf and corresponding PNF files.

6. In administrative tools-> services, find any AMD/ATI services and set the startup type to manual. (I won't detail how to remove services now).

7. Restart, when windows prompts you to install video card drivers, cancel the wizards that come up.

8. Download and install the correct 11.6 driver from here: http://www2.ati.com/drivers/11-6_vista64_win7_64_dd_ccc_ocl.exe

9. If it still quickly aborts, launch control panel -> system -> device manager. Identify the entries for your video cards (likely with an exclamation point icon). Double click on the item, on the driver tab, choose update driver or install driver, choose "browse my computer for driver software", and direct the installer to C:\ATI\Support\11-6_vista64_win7_64_dd_ccc_ocl\Packages\Drivers\Display\W76A_INF

10. If you manually installers drivers for all video cards, use windows explorer and browse to C:\ATI\Support\11-6_vista64_win7_64_dd_ccc_ocl\Packages\Apps\OpenCL64, and run OpenCL.msi

11. Restart. Mine.

Thanks a bunch for all the info, i am going to try this last since i spent about 5 hours down today from wiping windows once already, and i have a loan to pay back so i'm trying to keep downtime to a min. Muchly appreciate that bulk of info though, i may end up having to do this.
