On the strength of past experience with Windows Vista Ultimate 64bit edition and Terragen 2, i must say
that the Software runs very unstable. It took 7-10 minutes of work to crash.
Any other experience you have made?

Peter
Are you aware of the memory-leak bug in the latest release?
Using TG2 normally will make TG2 crash within that time-range for sure.

I've been using Vista-64 ever since the service pack update and it has been the most trouble free computer experience I have ever had. The problems with Terragen 2 have little to do with the 64bit OS.
Memory leak-bug??? ???
Could you tell me more about that problem?
PeterParker (aka Spiderman), the latest Alpha release which has only been released to registered users has issues. It's not something you'd want to use to base any sort of heavy outcomes. Something you should know is that until the next version comes out, 64-bit is not going to help memory yet. This is because TG2 has yet to have extra memory utilization programmed into it.
Hope this will be fixed in th final Version.
Calico explained it correct for me, keep in mind that this release is only availabe for regged users...
The only use for 64-bit systems is that when you have >3 GB RAM you can open >1 instances of TG2 which will have ~3GB for themselves each max (since TG2 = 32-bit).
Don't you mean >4 GB or RAM? For a 32-bit system, that's 32 bits per address, which is 2^32 which is 4GB. Sure, some is allocated for system purposes, but you still need greater than 4GB for any type of use on a 64-bit system.
Theoretical/Technically, yes :) But when it comes to practice it is easier to stay with 3GB, just for convenience, but you're right.
That's interesting Vista 64bit should theoretically be able to see all 4GB however according to this article http://4sysops.com/archives/why-windows-vista-only-sees-3gb-memory-in-a-pc-with-4gb-ram-and-how-vista-sp1-fools-its-users/ it reserves 1GB back for the Operating System.

For stability, yes the current alpha build is quite unstable, often crashing every 10 minutes or so, especially when dealing with the quick render restarting a lot. Thats known, its a memory leak, and don't think its some horrible thing that x64 causes and will be in release. They warn you on that version that its unstable and not fully ready. However, using the stable version for a quite a bit on 64bit i can say that i think it might've only crashed once, if that.
Any os will save some of its memory for the os, thats a given. vista allows for you to access more memory and not have your devices take memory out of your main memory. with a one gig graphics card of ram, plus 4 gigs of normal ram, windows vista 64bit showed me at about 2.3 -2.7 gigs of ram i believe of my 4. Thats what the OS can physically use, before it splits itself off some ram and then hands the applications some ram. I believe the max for windows x32 is 2gb ram towards app, 2gb is reserved for os (i think it keeps a 50/50 ratio but not sure) UNLESS the /3gb switch or whatever is used, giving the application a max of 3 gb and the os 1gb IF your detected amount of ram is indeed 4gb. 64bit programs have access to higher amounts of ram, but the 32bit inside vista is still limited to a max of 3gb i believe maybe 4... but thats to each instance of the program.
If your planning anything getting near the 3gb border of ram, i really just suggest going 64 bit. It just makes life easier should you choose to do some more upgrades you don't have to worry about other devices, and it makes sure all your memory gets registered properly, not cut out by how windows sometimes messes up its registration of ram. I also don't see why people complain so much about an operating system reserving itself some ram... it needs to have a certain amount of ram to run, and it keeps just a lil more so it stays responsive as it can to your moving stuff around.

the way you wrote this it sounds like you believe that x64 is being used in this article - it isn't... the problem is with 32bit and its solution it tells you to install x64 version.
I use XP-64 and I can use the latest build for a couple (3-4) of hours without problems, but as said before I can't use the preview-render that much. At a certain point of designing my scene I don't need the preview render anymore so that's just convenient.
Though after a couple of hours and lots of test-renders the memory still saturates and TG will start popping render-bucket errors. I then quickly save my work and restart TG2. That seems to work fine so far.

"The only problem is that those who are unaware of Vista's 3.12 GB limit just wasted their money."
I wouldn't encourage anyone to use Vista.
From Microsoft -
For Windows Vista to use all 4 GB of memory on a computer that has 4 GB of memory installed, the computer must meet the following requirements:
• The chipset must support at least 8 GB of address space. Chipsets that have this capability include the following:
• Intel 975X
• Intel P965
• Intel 955X on Socket 775
• Chipsets that support AMD processors that use socket F, socket 940, socket 939, or socket AM2. These chipsets include any AMD socket and CPU combination in which the memory controller resides in the CPU.
• The CPU must support the x64 instruction set. The AMD64 CPU and the Intel EM64T CPU support this instruction set.
• The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect (PCI) configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer. View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature.
• An x64 (64-bit) version of Windows Vista must be used.
Contact the computer vendor to determine whether your computer meets these requirements.
Note: When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating system is always less than the physical RAM that is installed. For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install 8 GB of RAM, the system memory that is available to the operating system will be reduced by the PCI configuration requirements. In this scenario, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately 200 MB and approximately 1 GB. The reduction depends on the configuration.

I use TG2 on Vista x64 regularly and it works fine. It is likely that your problems are due to the memory leak or other issues with the "unstable" Technology Preview 3 release. The memory leak and many other issues have been fixed in internal builds and a new Technology Preview or Beta will be available in the coming weeks for registered users.

Thanks a lot for the answers. So we are waiting for the Beta to come :-)
Win Vista 64 runs stable have no problems so far.
Thanks a lot also to Oshyan for this lovely message :-)

I've recently started using the latest Alpha with Vista 64bit, and once I'd upgraded the graphics drivers I've had a sweet experience. A couple of menu glitches maybe, which I think is more to do with my default font size being big.
