Hi All, I've just reinstalled RC4.3 on my new PC with Windows 7 32bits. Everything went fine. However, when I launch RC, load a flight plan and launch it with FX ready, I have a message "IPC timeout". If I launch RC as administrator, it refuses to launch and says that COMDLG32.OCX or one of its dependancies is not registered, although I've donwloaded sevral versions and received successful messsaegs of registration using REGSRV32 in admin mode also. Could someone help me please ? That would be so appreciated ! Cheers, Mat
