Error: Unable to obtain hardware information for the selected machine.

Here's an odd problem I've found in VMware vSphere 4.1 while trying to export a VM. When wizard for export was called, it runs a hardware inspection, and I couldn't get thru it because it was showing that error:

Error: Unable to obtain hardware information for the selected machine.

Like any respectable sysadmin, I googled the solution, but I could only find vConverter stand-alone issues regarding VMs registered as Windows 2008 R2 and software not being able to handle that, so a change to Vista 64 was needed. However, this was not the case.
