Issue Details

I have LabWindows/CVI 2009 installed. When I try to open the software, I see the splash screen but the application never fully opens and closes immediately.


This is a known issue caused by Bug 239396. It was resolved in LabWindows/CVI 2010.

If you are unable to upgrade, refer to LabWindows/CVI 2009 and 2009 SP1 Known Issues for the workaround. If you select the registry key option, always make a backup of your registry before making any edits.
