IP MegaWizard problem

Hey all,

I want to add FFT IP to my project. When I choose FFT v.7.2 from MegaWizard Plug-In Manager->DSP->Transforms->FFT v7.2 the screen blinks and show me the same window again.

I am using Quartus 7.2 32bit, Windows 7 64bit.

Does anyone know how can I solve this problem?

Thanks Ahead
