I've got a problem that just started with RC4, I'm running fsx on win7 64bit, on a stable I7 960 OC 4.0 with no outside problems. RC just gave me an error tonight two times:Runtime Error 76RadarContact.fsuipc.rcv4codeWhat I am doing so far, (let me know if I am over looking anything, won't know till tomorrow, when I get up, it's late here and have to get some rest first)Update FSUIPC to 4 4.60disable Norton Antivirus 2011updated RC4 database.Anything else I may have missed? I'll post back with or without the error, trying to get from KDEN to KPHX. Miklos

Error 76 can be caused by timing problems or lack of RC access to FS via FSUIPC.One of the most common errors is to insure FSX is running with a flight loaded usually parked at a gate.To run RC as an admin it is easiest to set up a shortcut to it with the privilege set to run as admin in the shortcut. In Win 7 turning off UAC does not disable all of UAC protection.In the thread about antivirus applications at the forum top you'll find a reply about setting up Norton to trust RC. Norton may not let you disable all protection by shutting it down. Tell us what add-ons you are running and if on a network (WideFS) where your applications are. Are you running ASE? If so be sure that is up to date.Here are links to update all of the FSUIPC and WideFS base and interim version, plus makeryws:-----------------Get the base FSUIPC version from:http://www.schiratti.com/dowson.htmland then interim update from the modules link on this page:http://forum.simflight.com/forum/142-download-links/From that download link page under the Additional Programs link get the latest makerwys.exeFSUIPC now self installs initially based on your registry entry for your FS path. Check that with this free utility:FSX/FS9 Registry Repair Tool (36KB) from http://www.flight1.com/view.asp?page=libraryAfter getting FSUIPC installed and then makerwys.exe installed in your FS folder start RC and rebuild the scenery database.If you have both an FSX and FS9 installation two RC4 folders were created. Be sure you have two shortcuts for each RC version to its respective folder for each FS version. (VISTA and Win 7 users will want for each shortcut set its advanced properties to run as admin.) Rebuild from within each RC version the scenery database.
