I have tried to open quite a few OVF files using VMware Workstation 7.1 and VMware Player, but I keep getting the error such as “Failed to query source for information” or when trying to import the OVF file – “The OVF descriptor file could not be parsed”. Not sure why this is not handled correctly even with the latest version of VMware software.
I found that if you convert the OVF file to a virtual machine using the VMware converter it works fine.

Your export came out as OVF 1.0 format and Workstation 7.x doen’t understand anything above OVF 0.9. You have to use the OVFTOOL to make the transition of your VM to VMware Workstation.
