Cannot instal Native Instruments guit rig

Hi Guys

I have N.I. guitar Rig and I cannot install it on my PC.

Ihave tried installing it on other peoples PC and it installs fine. But Not on mine.

Running Cubase SX3.

I have installed Native Instruments FM7 Synth but having a hell of a time with Guitar Rig.



Each time I try to install the set up.exe file it just hangs on me.



MY system

P4 2.8

1 gig Ram

windows XP Pro

40 gig Hard drive primary D/drive

80 gig Hard drive secondary. E/Drive

Asus P4C 800 Motherboard

using generic soundcard.

also using Maudio 2496 soundcard.





Any Ideas please

regards

RC
