Right, I run 32-bit Windows, and have tried the environment variable - it didn't work. Hmaster.exe is the executable crashing, and I can't run the License Administrator. And re-installed it a few times.

The former. Every time so far (over a dozen attempts, including uninstall/reinstall at least four times)

I've searched through the boards and found that 1.) this is a common problem and 2.) the commonly suggested fix doesn't work in my case.

Problem I run Houdini Apprentice. Splash screen appears, and then I get the Windows “This program has encountered a problem and needs to close” error. I've tried both build 295 and 375.

System specs
AMD Athlon 3.0 GHZ dual-core
Win XP Pro
4GB Ram
Nvidia Quadro FX 3800

Other 3D apps I run Maya, ZBrush

I've got release 190.38 of the nVidia drivers, so I'm honestly stumped.
