I had the problem with the converter 6.2 ... there is no longer a converter-worker.xml there is only one singel file - converter-client.xml
so I entered the SSL option code, then the converter could connect... and then I tried to convert a VM and it spit into my face with a message "cant read hardware settings". wtf?
I belive it can't by design... and this has to do with some no longer supported storage configurations. With the other direction I had to hack the vmx files, then the converter 6.2 did convert my player 6.5 VMs... the root cause was a vmdk file pointing to a physical disk. But I wont touch my "golden sample" which contains 5 years of lessons, research and tests. And there are only iSCSI or local volumes...
I have to say today I lost my faith in VMware products... also because of a purple screen with an original and vmware supported Intel Quadport E1000 card in a VMware supported mainboard...
