Hi All,
Well, given the amount of uncertaintly arround my likelihood of success using repair (which was my 1st intent b4 reading this thread), and not having the time and inclination to do an uninstall and reinstall, I restored the ProgramFiles\...\Labview8.5 directory from a weekly system backup. Thankfully this seems to have restored things.
I initially tried to just restore the error.llb file since the General Error Handler Core.vi seemed to be the root of the problem. Restoring the error.llb did not work. The initial error that caused the crash that led to the broken library still occurs.
This crash had to do with dropping an error probe when doing a debug of a RT exe. I have sent through screen shots and a dump log to NI and hopefully I'll get some info.
To me this is a SERIOUS PROBLEM. I am quite ready to live with the occasional crash that requires a reboot but a crash that corrupts the tool and requires a full uninstall and resintall is just not on. Installing Labview and all the modules that we use is a 1 day job!
Does anyone know who might pick up the ball on this. I am happy to provide the project and any info I can. There are limits to what I can post in terms of code as some stuff is covered by confidentiality but I can supply the code to NI as required.
The one thing I can say is that backups are a life saver. The restore took less than 15 minutes. Heaps better than a day with an install. Uninstalling takes time too.
Have a good weekend all.
