3d studio max 7.0 installation problem!

Hi there,

I am using windows service pack 2 , when I try to install 3d max studio 7.0 , a message pops up saying it requires directX 9c or later version , to setup 3dsMax.

So I went to microsof.com and downloaded directX9.0c and tried to install, but then again another message popup say directX9.0c already installed in the pc. Where as I am unable to install 3dsMax in my pc, could some one help me with this problem?

Note: It works fine with service pack 1.
