WinXP SP2 and nForce2 tweaker

[trodas]

Curse the damn SP2, curse them!!!

First - there you can download nForce2 tweaker, a usefull (highly) tool for professional (do NOT tweak if you don't know what you are doing!!!) overclockers:

It does run on any chipset, just don't try the button Set, please.

As you can see, it is a zip archive and containing the IO.DLL file. Nothing wrong with it, just copy it to the system32 directory and it will run - except you are running on the damned XP SP2 crap.
Win2k SP2/3 and WinXP SP1 run fine, but SP2 complain:



and then



Well, Im admin and why in the name of God I can't run normal software, that is beyond my understanding. Can anyone enlighten me, how to make THIS work?

I understand that it probably require some tweaking of the security settings, but hey - what to do? I don't like the idea of installing XP SP1 just to make it work, so I hope someone can help me to archive the goal quicker.

Thanks for helpfull responses - and if some explaination WHY this is happening will be done - the better.

PS. I tried register the dll:
regsvr32 \windowns\system32\IO.DLL
...but it does not work/help at all...

Help???
