Hi all, I got a problem installing the OptiTrack SDK (1.3.035) on Windows Vista. At a certain point the setup says that the OptiTrack.dll file didn't self-register.

I continued the installation but then I got access violation problems in starting the C sample application.

I tried then to run regsvr32 "C:\Programmi\NaturalPoint
\Optitrack\bin\OptiTrack.dll" but it says that the call to DllRegisterserver didn't succeed (indicating error code 0x8007007e)

Am I the first with this kind of problem? Any hint?

Thanks

32 or 64-bit version of Vista?

32 bit version

I have also uninstalled the TrackIR 4 sw I had on the same PC and then installed the OptiTrack_1.x.xxx.5800.exe version the Support sent me to interface directely TrackIR 5 devices.

But nothing. Same problem, this OptiTrack.dll doesn't want to self-register and then the re-compiled demo app supplied in the SDK crashes at start
