Vista - Vista x64 and Icewind Dale

I'm trying to install Icewind Dale on my AMD dual-core based Vista x64 PC and
not having much luck. Although the CD will auto-start, when I choose to
install nothing happens. This is also the case when I double-click on
setup.exe in the CD root folder. I've also tried XP-SP2 Compatibility Mode
for setup.exe without success.

Strangely I can auto-boot and begin the install for the Heart of Winter
Expansion CD (which naturally fails because I don't have Icewind Dale
installed) without issue.

I'm not sure where to begin looking for a solution to this one so any
suggestions are welcome.

So with a bit of persistence and some research, the answer to this one is to
reboot into Safe Mode, install IWD and Heart of Winter plus the Trials of the
Luremaster update/patch and then reboot back into normal mode and run. Works
a treat :-)
