Is there any way to install a 64-bit version of Windows 7 on a 32-bit version of Vista as the host operating system using VPC 2007?

It keeps telling me my processor is not compatible with 64-bit, but I know it is. I'm assuming it's something to do with my host OS being 32-bit.

Thanks,
Adam

This message may be to do with the virtualized CPU not being 64-bit compatible, and not to do with your real CPU. Have you checked that VPC can handle 64-bit guest OS's? I think that it only runs 32-bit OSs but I'm not 100% sure.

Thanks silver. I did some further research and found out that VPC doesn't support 64-bit for guest. VMWare however does. :) So I'm installing right now.

regardless of if VPC can run a 64 bit version or not - as far as the host operating system is concerned it is 32 bit (even if you could have run a 32 bit it is not doing so), so would not, I think, be able to host in VPC any 64 bit op systems.

Ok, I decieded against it anyways since when I went to download VMWare Server they wanted my address and I'm just not willing to give that info to a company that I don't trust, such as them. I know they are legit but they don't need that anyways. I'll just have to burn it to a dvd and shrink my partition and make a different one for it and dual boot. :)

Thanks both of you.

Actually, it is possible, if your CPU has hardware visualisation. Most users won't have that though, it's more a company feature.

Host system really does not matter. The underlying architecture is what counts. Some systems need you to actually go into the bios to enable Virtualization Technology before you can install a 64bit guest. I run VMWare server on an IBM Thinkpad and the host is 64 bit Windows 7. I needed to configure the BIOS so that I could install a Server 2008 R2 guest.
