I'm trying to install a WindowsXP 64 bits in Windows Virtual PC. Windows Virtual PC complains:

Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode. Please install a 32-bit x86 operating system.

But the whole thing is running under a Windows 7 Enterprise 64 bits. How can this be? What coult it be the problem?

  • Why using old Virtual PC? Try VirtualBox. – Biswapriyo Feb 21 '19 at 20:32
  • because it was there, but I guess I will have no other choice than to download a new one according to what the answer says – user21384 Feb 21 '19 at 20:37

Windows Virtual PC does not support 64 bit guests.

See this chart. Note the complete absence of any 64-bit guest column. This hypervisor is emulation based, so you are stuck with whatever software they use to emulate the hardware/processor. If the emulator only emulates a 32 bit processor, you will only be able to use 32 bit OS and applications. Use another hypervisor that supports 64 bit guests, such as Oracle Virtual Box or VMware Player.
