Hi allUsing Windows XP (SP3), FS2004, FSUIPC 3.93.Having been using RC4 for few years, 100s of flights. However am now repeatedly getting Error 75 messages, and RC4 quits. I've checked other replies on this forum but all refer to Vista etc...Any help on what might be going wrong? Let me know what other information you need, this error happens at different locations, sometimes on ground sometimes in air.ThanksMark

did you define the .flt/.wx path? click the .flt/.wx button

did you define the .flt/.wx path? click the .flt/.wx button

Yes, however I have redefined the path, just in case for some reason it has lost the path to the folder it was originally pointing to. Will advise if the problem continues.Thanks for your helpMark

Hi JDUnfortunately still receiving the error 75 problem, even though the path has been set correctly.In fact the full error is "RUN TIME ERROR 75, RADARCONTACT.FSUIPC.RCV4.CODE"RegardsMarkHi JDI have tried same flight again, this time creating a log...This time the error changes to "Run-time error 52: Bad file name or number".This has happened on THREE successive flight attempts - I'm getting nowhere! :( Your help would be most welcome.RegardsMark

make a log, instructions pinned to the top of the forum. send me the log, and i'll tell you what's wrong.are you running vista or windows 7? are you starting rc by right mouse clicking the .exe or shortcut, and clicking run as administrator?jd

and what antivirus program?

and what antivirus program?

I'm using AVG 9.0

I'm using AVG 9.0

Hi JDI have tried the following things, within AVG.1. Adding RCV4.exe (by browsing to the application file) to the "Potentially Unwanted Programs Exceptions" list. Error 75 still occurs.2. Adding RCV4.exe to the "Resident Shield - Excluded files" list. Error 75 still occurs.3. Adding the path where the .flt files are saved to the "Resident Shield - Exludes directories". Error 75 still occurs.4. Disabling Resident Shield - which is effectively turning off the main elements of the anti-virus program. Error 75 still occurs.Although as I mentioned in my email, I thought that AVG could be the cause of my problems, as it has recently ugraded from versio 8.5 to 9 - this was about the same time as the FS/RC problems started; but as far as I know how to, I have allowed RC4 sufficient access to do what it needs to do.Mark

#3 may be the problem. you need to exclude "c:\program files\rcv4" (if that is where rc is stored), and the subdirectories. espcially, "c:\program files\rcv4\winwood\"

Changed the exclusion to "c:\program files\rcv4". I thought I was getting somewhere as I even managed to get airborne, until the error 75 appeared again, about 5 mins after takeoff.Is there any way I can test RC4's save routines from the RC4 application itself, rather than load up and start a flight, to see if it is able to save to the specified folder? If so, I may be able to check different settings on AVG quicker to find out where the problem lies.Mark

i guess you could go into the plane information screen, and press the speaker icon a bunch of times. that would create the wav file in \winwood each time. i guess you could go into the voices screen, and click the button for one of the voices, that would create a wav file over and over again.you could uninstall rc, install it in a non c:\program files directory.i used to use AVG, but not any more, so i'm not familiar with the new settings. maybe someone with AVG could jump in.jd

Hi Mark,I'm still running XP SP3 and FS2004 but I still use AVG8.5 on my two FS PCs. I've never found the need to add anything to the AVG exclusion list but perhaps that's only available on the purchased version. I use the free one. The only difference in our systems is I run RC4 via WideFS but there's still the requirement for RC to be able to write to FS folders.If things worked fine until recently was it only after AVG9 was installed that your problems started? You could try uninstalling it and see if that fixes the RC problem. If it does then it does point to AVG being the culprit. I've had problems with AVG9 on my laptop with email on Outlook so this version may also be causing other problems.Anyway, uninstall AVG9 and see if that fixes things. If it does then revert to AVG8.5 and raise the issue with AVG.PS. It seems AVG9 is responsible for disabling Windows Defender but the free AVG Forum has no-one available for any official response. If it's doing that then there's every possibility it's doing other undesirable things. I would definitely uninstall AVG9 as I think that is the source of your problem.

Hi JDThanks, tried speaker options with aircraft callsign and voices screen etc... that worked WITHOUT problems. Likewise the log files also saved OK - unless the error was caused by the log saving rather than a normal RC save.I will try other options.Mark

Hi RayI was thinking along those lines too... I too had been using the free AVG8.5 and never got a problem (nor had ever to add any files or paths to be excluded), and upgraded to the free AVG9.0 within the last week or so, and that's when the FS/RC problems started - or was that purely a coincidence??I had previously tried switching off the "resident shield" within AVG9.0 (this effectively disables most of AVG - and even triggers the Windows message about no firewall being detected on the system) - but still got the error problems when running FS. So I was starting to wonder whether this was an AVG problem or not.Anyway I've rolled back from AVG 9.0 to 8.5 and tried my flight again..... NO PROBLEMS AT ALL :( And that was flight of over 1 hour, plenty of time to allow the error message to appear if it was going to.So therefore I too am now convinced that AVG 9.0 is the problem, clearly its a lot more protective than previous versions, and much tweaking would be necessary to ensure FS/RC (and other applications) worked properly. I noted that AVG has a forum, rather limited - needless to say AVG official support seems to be reserved for their paid-for version.I'm going to stick with AVG8.5 for the time being, until I know of a definite fix with AVG9.0 and FS/RC.** Yes - I had also noticed that Window Defender seemed to stop for some strange reason lately, hadn't connected that with AVG9.0. Hopefully another problem solved then.Thanks Ray - and JD - for your help and assistance on this problem.Mark
