Can't Install nTune

[iLace]

Hey guys wondered if anyone can help me out.
Trying to install nTune and I get two errors during installation.

1. I already have these files on my computer.
2. This doesn't support your mobo.

My mobo info is:
Manufactor: ASUS
Model: P5N32-E SLI PLUS
Chipset: NVIDIA - nForce 650i SLI SPP
Southbridge: NVIDIA - nForce 570 SLI

Other info:
vista 64, q6600 (no oc)
4g ram
8800GTS (g92) - latest drivers

Edit: Just found out error 1 is because ntune is half installed. It wont open and work
but it wont delete either. I found the folder "nTune" and deleted the contents but two
files wont delete apparently i need permission.... Im admin and UAC is off...
So they are there... can't be deleted manually or in add/remove programes...

Kind of digging myself a hole here, any help will be much appreciated.

Try booting into safe mode and deletting the files.

Then go to nvidia's page and download the latest version (check it's a 64 bit version) and try to install again.

(also a registry cleaning program may help removing some remaining registry keys from the previous installs that may be causing troubles)
