It is disabled and both windows 7 and xp is 64 bit.Hello
Can you please try disabling Hyper-V from the Windows Features box from Control Panel and see if it helps?
Also, please ensure that you're running 64-bit variant of Host operating system, or if the Host OS is 32-bit, please make sure that the guest operating systems on VMware are 32-bit as well.
Good Luck!!
