I have an old vmc file that fine for years with Microsofts VirtualPC. I just converted to Windows 10 and I found out that vmc are no longer supported.
I was hoping VMware had something to convert/run vmcs, so I downloaded VMWare Converter and pointed the wizard to my vmc file and within a few seconds I get a "A file I/O error occurred while accesssing ". error. The file is a local file and I'm running this in Windows 10 64-bit. I tried to convert some previous backup vmc files and they all give the same error at the same point. I don't think the vmc files are corrupted as they were working a few weeks ago.
