cubase 5 on snowleopard

Hi,



My macbook pro runs now SNOW LEOPARD and i have trouble to install CUBASE STUDIO 5 on it ?

Its a original cubase studio 5 version i bought a long time ago, used to work fine on my old OSX

Now It keeps saying installation failed…

Does CUBASE STUDIO 5 run on SNOWLEOPARD ?

I tried updating to higher versions of cubase, but that doesnt work if you cant install the original package first.

Should i install my old OS X , than install cubase 5 and upgrade ?

Thanks for helping

Or wont that work ?
