Thanks Armstrong. As far as UR on 64-bit Win 7, I am primarily interested in compatibility which Kinook has now confirmed. Your original post asks about performance impact, but I was/am not expecting a significant performance impact (also commented on by Kinook).
I've upgraded several database servers at work to 64 bit OS. This was due to need for expanding memory headroom for large databases and/or memory hungry apps. Applications performing adequately within the 32-bit address space (4 GB minus overhead and restrictions depending on Windows Server edition) remain at 32-bit.
Getting back to UR and personal computers, UR is currently using less than 10 MB on my system, so it doesn't need additional memory.
However, like you I am interested to hear any Win 7 64-bit experiences in general. As you probably know, the potential downside of 64-bit and any new OS is application/driver compatibility. This has become less and less of an issue over time, but is still a concern. (Good news that UR has done well in testing.). In any case, Win 7 Pro and Ultimate will have an XP compatability mode just in case (basically a virtualized 32-bit XP environment from what I understand).
BTW, I've been waiting a long time to jump into 64-bit OS. The time is finally right for me with release of Windows 7 and better driver support. I run memory-hungry applications such as SQL Server, Visual Studio and VMware running multiple guest VM's. Also, my new system will have an SSD sys drive along with a larger conventional RAID-1 array for data. With 6 to 8 GB of RAM, paging to those drives will be reduced (another design goal).
Your decision to stick with 32-bit XP (or Vista for those already running Vista) really makes sense for most people. I'm currently running XP myself and would not bother to upgrade if I weren't building a new system.
