Chad,
The 0xC0000005 error as reported by Windows is a generic error that often hard to track. In this case I'm working under the assumption that there has been a problem with the installation somewhere. However, did MAX work properly before you installed NI-Motion, or was the installation of NI-Motion the first program you have on your system to interface with MAX? Since you have tried a number of times to repair the installation by a simple reinstall with no success, I would recommend trying this method:
1. Shut down the system and physically remove the PCI-7344 from the system (important to remove resource locks).
2. Restart and uninstall NI-Motion and Measurement & Automation Explorer (MAX) using the Add/Remove Programs Applet in the Control Panel.
3. Restart and reinstall the drivers for NI-Motion - this will also add MAX.
4. Shut down and physically reinstall the card.
This fixes the problem in 90% of cases similar to this, but there could be other causes such as something related to your system (eg BIOS revision).
Let me know how this works for you.
