PAE-enable problem

I'm using VMware Workstation 3, and when I tried to turn on a virtual machine this message showed up: "The host operating system is using the Physical Address Extension (PAE) processor option. VMware Workstation currently cannot run on a PAE-enabled host. Please disable PAE in the host operating system and restart VMware Workstation."

I posted a message earlier and get a reply to open the virtual machine's .vmx file and add "paevm="true"." I did just that, but still not able to turn on any virtual machine on my AMD Athlon 64 processor computer.

Is there any other way to get it working smoothly? Please help....

thanks.

Re: PAE-enable problem

The processor is running data execution prevention (DEP). If you are running Windows XP SP2 it will automatically enable PAE to support DEP. VMware Workstation 4 and higher supports PAE. So, if you want to take advantage of DEP I would recommend upgrading to the latest version of VMware Workstation. If not, then take a look at the boot.ini on your host OS and look for /noexecute=. It probably looks like /noexecute=optin. If so, try changing it to /noexecute=AlwaysOff. This will disable PAE and support of DEP regardless of whether or not the processor is running DEP. I hope this helps.
