first post to this board

Well, I'm not able to get houdini to run on my ubuntu 9.04 32 bit system. Installation works fine until I type “houdini” to launch the app. Then it says “cannot execute binary”. I assume this is a 32bit/64bit issue?
At the download-page for the apprentice there's no way to say whether you want it for 32 or 64 bit. Should that file work on both? I'm a bit suspicious since it says “64” somewhere in the filename of the file I downloaded…
I hope there's someone who's had the same problem and solved it somehow

Greetz,

edit: yes, I spent some time searching this board but I didn't find a solution. If there is, point me to the thread please


Is there a rule of thumb which driver-version works best with houdini? I'm using a Geforce 9600M GT.
