How about a new product incorporating the motion tracking technology used in the Nintendo Wii? No webcam required!

Hey Vincent - my troubles returned - can you believe it? I did a step by step uninstall and found the culprit - it was Active Sky X... My system is now sweet and stable so I am going to use an alternative weather system from now on!

Have a look at your Graphics card settings - my ATI Tray Tools has this as an optional feature...

<t>I think I may have caused the problem when uninstalling various items from my computer. I may have caused shared files to be removed...<br/> <br/> I have reinstalled Windows, etc etc and now all is well.<br/> <br/> A little knowledge is a dangerous thing...<br/> <br/> Thanks for your help Vincent...

<t>Vincent, after much investigation and head-scratching I am beginning to suspect Visual Studio as the culprit. I am going to install the latest service patches and hope it restores MSVCRT.DLL.<br/> <br/> I'll let you know...<br/> <br/> Also - many many thanks for your time and effort on this - esp...

Did that, same problem, same dll, same instruction. 1 minute into default flight- bam.

I do not believe it is the TrackIR software Vincent - I have been using it for ages. Maybe my copy of the dll is corrupt...

<t>I use FSAutoStart to terminate most of the TSRs so there is precious little running with FSX. Rig specs: Acer 9504 Pentium M760 2.0Ghz,2 Gb RAM,Win XP Home, ATI x700 256Mb.<br/> <br/> TrackIR.exe bombs out at 0x77c4cb5a after about 30secs - 1 minute of flying. I have uninstalled .NET Framework 3....

I am using AVG - which I have disabled.

The error message is:
Unhandled exception in TrackIR.exe (MSVCRT.DLL) 0xC000001D: Illegal Instruction.

Once the dump occurs (in FSX) the software remains unstable in other games until reboot.

Vincent

I have found 3 installs of MSVCRT.DLL, one in c:\windows\system32 and 2 in the winsxs C++ folders. Which one is used by TrackIR.exe.manifest?

No joy.

All ok with SFP1. Flew for 10 minutes.

Then swapped for FSX and the crash occurred even before the flight had finished loading...

Looks like FSX is the problem.

Do I need a new copy of MSVCRT.DLL?
