No>luck....I had the same problem and, as maybe someone needs it, I'll tell you how I resolve it (if you can understand my Tarzan english :-roll).I had installed FSUIPC 3.60 and registered it, but when I try to start RS4, I receive the message "Incorrect FSUIPC version or not FSUIPC"... (my fault, I had no started FS9). So I come to the forum and I see the topic "FSUIPC 3.617 has been released *** THIS IS IMPORTANT **...". I downloaded the FSUIPC 3.617 and copied the .dll into the Modules subfolder. But when I start RC4 I receive the same message again.Anyway, after a lot of brain work :D I try this: I look into the FSUIPC.log file and I see a suspect "FSUPC ver. 3.60"... So I quit this file and the FSUIPC.key and now RC4 works :D.Surely the .log and the .key files point to the older FSUPIC.dll.I hope this helps to anyone who have the same problem (and I hope you can understand me).
