Hi,
Oh, it is the correct answer, but at the moment I don't know where to show you this on a publicly available page.
From the End User License Agreement (EULA):
2.3 Copying Permitted. You may copy the Software and Documentation as necessary to install and run the quantity of copies licensed, but otherwise for archival purposes only.
So unless your license is allowed for multiple copies (The Type field would say "Volume" in your help -> About box) you can only run 1 copy.
See for an explanation here:
Obtaining the Workstation Pro Software and License Key
You can find your copy of the EULA here:
C:\Program Files (x86)\VMware\VMware Workstation\EULA.rtf
