Thanks for your suggestions! However, I have already loaded the MFC package you suggested, and I do not use ports below 1024. I attempted to run from the command line and received the following information: fixme:ole:CoInitializeSecurity ((nil),-1,(nil),(nil),0,3,(nil),0,(nil)) - stub! err:ole:ProxyCliSec_SetBlanket (0x138b64,10,0,(null),3,3,(nil),0x0): stub err:ole:CoSetProxyBlanket -- failed with 0x800004001 Could not set proxy blanket. Error code = 0x800004001 So that looks like a pretty good clue, if only I understood it! I went to winetricks to see if I could find anything related to OLE but didn't.
