Virtual PC x64 on Windows 7 x64 host

Hi!

I' running this system:

- Intel P8600 with VT-x enabled
- Virtual PC SP1 x64
- Host: Windows 7 Beta x64
- Guest: Windows XP Pro SP3 x86
- Virtual Machine Additions installed

Questions:
- Why does VPC install on Program Files (x86) instead of just "Program
Files", since the host is Windows 7 Beta x64?
- Why does VPC run in 32 bit mode? Process in Task Manager shows up as
"Virtual PC.exe *32"
- The guest Virtual Machine - Windows XP Pro SP3 x86 - is very slow! The
same machine running on VPC SP1 x86 running on a - Windows XP Pro SP3 x86 -
host is perfect.

Windows 7 is still in its initial beta phase - you can't realistically
expect it to be 100% ready yet...

VPC is a 32 bit app.

Re: Virtual PC x64 on Windows 7 x64 host

Thank you both for your answers

@Mark Rae

I wasn´t expecting it to be perfect, just wondering why I had installed the
64-bit version and it was running in 32 bit mode in a 64-bit OS host.

@Bob Campbell

Your're right! It is a 32-bit app! I wrongfully assumed it was a 64-bit app
because of the filename and that there was also a 32-bit file for download...

I'll be waiting for VPC 2007 SP2

I answered that by providing a link to the section of the FAQ which relates
to that - the "perfect" comment related to your question about the speed...
