Welcome to the Community,
let's start with some clarification. You are posting in the ThinApp forum, does this mean you packaged VMware Workstation 9 and have issues with running the package or did you simply post in the wrong forum?
Please also provide some details about your hardware (e.g. CPU) and the virtual machine (guest OS) you are trying to run. In addition to this, attach the virtual machine's latest vmware.log file to a reply post to see whether this contains any useful hints.
