When I plug in the device it is being detected and installed (some default driver). But when I try to install the newest Software (3DxSoftwarePE_v3-5-6) I'm getting these errors:

Installation Failed
Error number: #

It never installs it correctly if I click yes. As far as I checked it looks like that it rolls back the whole installation and only leaves the folders and some help files and dll's.
I'm running Windows Vista Ultimate as administrator. I tried installing it directly with admin privilegs and also using Vista's Compatibility-Assistent for Windows XP SP2. I also tried to use the repair function.
