Tip for Running D3 in Windows 7

[Ishtvan]

So if you just install D3 under Windows 7 64, it runs but with heavy flickering and sluggish control input (flickering is not fixed by turning vsync on).

 

I read some forums, and saw various suggestions like run in compatibility mode, update drivers, etc. When I updated to the latest Catalyst, it wouldn't run at all complaining about "can't launch OpenGL."

 

The suggestion I saw that did work for me was to install it in XP (already done on my old HD), then just run that executable from within Windows 7 (so no install under Win 7, no compatibility mode or anything). This worked. Hopefully this helps anyone else with that problem.

That is so wierd... so basically you can install it somewhere, and then copy the folder over to somewhere else and run it and it still works? Essentially that's what's going on if you install it in XP then run it under Windows 7, since it can't possibly have access to any of the special "install information" it puts in the XP registry etc.

I've had weird issues with Vista/Win7 in which programs installed to Program Files dir or other "protected" locations have weird access policies on them. Some files are unable to be copied to the location, unable to be modified etc.

I was able to get around this by running the installers as Administrator and installing them to the root (C:\ ) instead.

I had it in a separate, non-OS partition both times.

Haha, weird.

I have mine installed (through XP) on my external harddrive. So this gives me hope I can just run it right off the harddrive like I am now whenever I upgrade to Win7.
