Hi, I'm using Labview 2011 with SP1. The OS is Win 7 32bit. Every time when I, e.g. I use the DigitalIO Example, send a command to the U12 labview crashes down and I can only close it with the task manager. The Labjack software LJconfig and LJtest are working but the LJ logger crashes down, too. I Think that the driver is faulty Does anyone of use has an idea? Thanks a lot Schorsch

Make sure nothing is connected to the U12 for troubleshooting (except USB).

Have not heard anything like this, and no problems with 32-bit Windows 7. You can try reinstalling the U12 software:


... but I doubt that is the issue. I am more suspect of something unique about that computer. Can you try some different computers, different OS, different USB hubs, and different USB cables?

Also, you said LJlogger.exe crashes. What if you disconnect the U12 before running and let it run in demo mode?

I found my mistake. The U12 is connection to another planing and I mirrored the sub d connector so it doesn't functioned. Thanks for your help
