OS: Windows 7 Enterprise

Created a virtual Pc with XP professional. I can duplicate one working copy of this virtual pc using XP-More. The original and the copy both work. I can open borth of them at the same time with no problems. I then created a second duplicate Virtual PC. When I try to open the second duplicate I get an error:


Could not register the virtial machine.

The virtual machine configuration could not be 
added. Another configuration with the same name
already exists.

I tried this several times using diffrent names. I can only create one duplicate working copy.

Thank you in advance for your help.

Hi digitalwiz,

Try the following:

  1. Go to the VM folder, where the vmcx files are (say C:\Users\digitalwiz\Virtual Machines or so).
  2. Delete the vmcx file of the erroneous duplicate.
  3. Go to the folder where the vmc files are (say C:\Users\digitalwiz\AppData\Local\Microsoft\Windows Virtual PC\Virtual Machines or so).
  4. Double click the new duplicate's vmc file.

The vmcx file is mostly a shortcut to the actual VM stuff, so deleting it is safe. When you launch a VM via its vmc file, if no vmcx file is found, one will be created. So once the VM is launched, you should have no problem using the created vmcx from point and onward.
