I did uninstall VMware Standalone Converter v4.0.1 and installed VMware Standalone Converter v3.0.3 Starter Edition. The restore job still failed, BUT when I followed the advice in this link:
http://seer.entsupport.symantec.com/docs/321059.htm , which was to cleaar the configuration checkbox and NOT add the VM to the inventory on the ESX server, the job succeeded.
I can't tell you which of the two changes actually worked, but I believe it was a combination of both, because I'm quite sure that I had tried the job with the check box cleared under v4.01 with a resulting failure.
Thanks for helping me.
