Does this work in Windows XP x64? If so is there anything special that needs to be done as opposed to the execution of the patch in Windows XP x86

I used this in XP and now i'm on Vista, I gotta say a big thanks to aion cause' I'd have to play my games on xp if he didn't make this. 

The acceleration fix is known to trigger a virus alert.  This is a false alarm.

Yea I ended up just putting it on the safe list.

Btw, what is actually the better fix? If it is suppose to remove acceleration why does it then seem to become faster upon application?
I used to use the CPL mouse fix but was wondering whether it was possible that the CPL mouse fix effect's somehow faded. It seemed like when I applied the CPL mouse fix it would work for an hour then I would start feeling acceleration again, and it would be noticeable - is it my mind or is the registry fix flawed? Whereas with this fix, even though its more responsive it seems stable and doesn't 'fade' or change.
Is this fix actually better than the cpl mouse fix?   I'm inclined to believe it is but I would love some confirmation on the two things.

P.S.

Great work, not many have posted but there are plenty of people out there downloading it and I hope you continue your work in refining it if needed.

Hello,
I have read through this whole thread and have tried to do a few things to get this to work on my computer... I can't get it to go.  I run the 32 bit windows vista. 

The one thing I havent tried is that deadlock thing that you suggested because the link is dead.  I don't know if it is necessary to use deadlock anymore or what. 

When I try to run install.exe as an administrator it instantaneously says installation failed.  and in the cmd it says that the requested service has already ben started.  I checked to make sure that it wasn't already working using the autoruns program and wcafix is not showing up in the list. 

I haven't really seen any direct posts on how to go about installing this for 32 bit vista, so I was just wondering if you could give my noob self a hand and give me a quick walk through (or if all i need is the deadlock, that would be great if we could get a new, live link) .

Thank you so much for your time,
Gwysota

Edit: Wow,  I just found it finally on autoruns. Thanks, but I don't need help now. Sorry!!

Yeah, it's awesome isn't it!  WinXP (not sure about Vista) had a bug whereby "Enhance..." was always on unless DirectInput was used (and only later games started using it).

   
Pointer Ballistics for Windows XP http://www.microsoft.com/.../archive/pointer-bal.mspx
"7. If the feature is turned off (by clearing the Enhance pointer precision check box underneath the mouse speed slider in the Mouse Properties dialog box [Pointer Options tab]), the system works as it did before without acceleration. All these functions are bypassed, and the system takes the raw mouse values and multiplies them by a scalar set based on the speed slider setting. "

ok so if i play counterstrike i need it to disable mouse accel. but the games that doesnt re-enable enhance pointer precision. do i still need the patch in those games? isnt it enough to just untick the box in the settings?
