I've recently installed RC v4.3 in my Vista system with FSX (SP1). Using the 'Voices' screen I get the message "Run-time error 75: RadarContact.rcv4module.pilot_ack" after clicking on any of the pilot voice playback buttons (similarl result with controller voice, etc.), and RC closes when I click 'OK' on the error msg box. I have the current 4.12 FSUIPC and am not using WideFS. Note that voice playback (Ground call, etc.) works fine with Level-D's 767 on my system, so I don't think the problem is with the Creative SB X-FI. Any ideas?Maury PrattEditor-at-Large,AVSIM Online

on just one voice? all voices? the error occurs when you press the button to hear a sample?try running rcv4.exe as administrator. see if that makes a differencejd

Same error occurs with all the voices. I'm logged on as Administrator, but no joy. Happens when button is pressed to hear sample.Maury PrattEditor-at-Large,AVSIM Online

I also found same problem: Error 75 with "RadarContact.fsuipc.rcv4code" when in FSX and selecting menu items ('1', '2', etc.). RC closes each time.(FSUIPC multiline display window is selected, and appears to be functioning properly.)Maury PrattEditor-at-Large,AVSIM Online

sorry you're having these problemsfollow the directions pinned at the top of the forum, create a .log, duplicate the problem, and send me the .logthat will help me troubleshoot your problemjd

I have same problem RC4.3 installed from your latest download to Vista Fsx sp1.This version has no dbug button so no .log to send.Trust .log has been sent by original senderbaf

run as administrator (doesn't matter if you are logged on as administrator - that still runs as a user context in vista)jd
