It installed without issue on Windows 7 64bit.

Runs fine for me in Windows 7 64bit + Windows 7 32 bit.  Possible driver issue with the OS bsased on your hardware?

another wonderful case of user error.

I've installed it on three Win7 machines, none needed neither Impulse nor Demigod to be run with any compatability modes.

It's most probably a driver problem, what graphics card / sound card do you have and what Windows 7 driver. I found I had to hunt for a sound card driver for windows 7 and it was a beta.

There really isn't much difference between Vista and Windows 7 as far as most applications are concerned, it's mostly Vista with much better memory management, less intrusive security and a couple of nice but unimportant new features.

The beta hasn't had any problem with any game I've played on it yet.

Oh by the way XP compatability mode is for business software and doesn't support Direct3D and things like that. Try without compatability mode.

What he said.

I originally had it installed on an x58 mobo, with a gtx 260, i7 920, asus xonar dx card...however, windows 7 is now running my htpc with a 790gx chipset, radeon 4770, creative xfi xtreme audio, athlon x2 5000+.

After I installed Windows 7, I could not run the game either - come to find out it was a graphics driver issue.  The installer for my Radeon 3850HD installed everything but the most important piece, the graphics driver.  I went into device manager and updated the driver manually.  After that, Demigod has run flawlessly.

I can say that I have an older setup and about midgame on Cata, my simspeed would drop to 1 or 0.  Now on Win 7, I start at 5 and it doesn't drop below 3.

All the flaming this game gets about how it was released, it's nothing compared to how Vista was sent out!  

That's because it's mostly the fault of hardware and software manufacturers, not MS

Try to download the impulse version. May help. who knows...

Also, are you working with the RTM version of Vista, or one of the RC (or earlier) builds?  That could very well impact your ability to run the game. 

Windows Update doesn't have all the 0day drivers ofcourse. If you install newer ones yourself you shouldn't let WU install them again for you. Drivers are recommended, but not critical updates, you you can chose to install or not install them.

Also I wonder what all those people do who claim they get lots of errors or less errors then before Other than faulty hardware I get no errors and didn't get any errors with XP either, so I could not comment on # of errors. I had none, I have none
