If they were to give me a version that logged to a file and asked me to mail that file to them then I would be more than happy to try and help them work out what's happening.
Look at the ANRB.elf file.
You could also look in the Vista Reliability Monitor. The last time anrb.exe failed on me was back on 12th July 2009 !!
I have not had what Vista regards as a failure, just one instance of the hardware disconnecting when I first ran 3.06 after about an hour or two I think, since then it's been OK.
I've just re-downloaded the installer, the one I got on Saturday 3rd October was 127,815,051 bytes, the one downloaded today is 127,747,746 bytes. So there has been a change in the installer, but I don't know when that new version was provided.
Tarbat, excuse me for not being very Vista savvy, but what is the elf file for? I have one called anrb.elf and another called anrb_old.elf, so I suspect that replacing the .exe and getting the "can't find the publisher" error is in some way related? Ah, right, I see it's a Eureka log file and that is the output of a Delphi debugger. So, do I need to send these to Airnav or are they uploaded to them via the server communication?
