problems running icewind dale 2 on vista

I'm having problems running Icewind dale 2 on vista. I can get Icewind dale 1 to run perfectly fine with no problems but Icewind dale 2 just doesn't want to work. I tried running it in compatibility mode as administrator but that just causes a "Icewind dale has stopped working" message as soon as I try to boot it up.
when I do not run it in compatability mode it works up until i bring up the in-game character menu then it shows the "icewind dale has stopped working" message. I had it working fine for awhile then i got the messages again. I didnt change any of the settings in between sessions either so I dont know why it decided not to work again.
If it helps I am running it on windows vista x64 home premium service pack 2 with a AMD 2.4 GHZ quad core, and yes i am running this under an administrator profile.

I am running 32bit Vista home premium and have no problem playing Icewind dale 2 but I do get in-game slowdowns, sometimes they get so bad that it becomes unplayable but has never flat out crashed for me.

Perhaps it has something to do with your 64bit system setup if its crashing straight out, its rather difficult to get some of these classic old games to work on newer systems. I've done some looking around on-line and the ideal setup seems to be to have a 32bit system and disable directdraw (to fix the slowdowns) but can't seem to be able to do it in vista.

Have you tried redownloading the Game?
Check you have enough space because it may take up alot of memory.
Another thing is to download all updates on your computer and check for driver updates, alot of peoples problems in Game are usualy graphics or memory problems in my experience

i've found the solution to the slowdown problem i was having, i downloaded the DirectX SDK from microsoft and used the dxcpl (directx control panel) application to disable the "use hardware acceleration" function, doing this fixed the slowdowns in the game and some graphical anomalies that were appearing in the fog of war.

just have to remember to enable the emulation once finish with the game session lol
