Labview 8.0 crashes when opening projects

[Tom Y]

Hi,

We have had labview 8.0 running fine under windows for months.  But now suddenly it refuses to open project files: when I open an existing project or create a new one, all labview windows just disappear without a trace.  Anyone seen this before? 

It runs VIs fine within labview and everything else seems to work ok - but I need to use projects so that I can generate executables using the application builder.

Hi Tom Y,

A potential source of the problem may be the service pack version of Windows XP. This customer had tried repairing, reinstalling, MSI Blast-ing, and deleting the registry files, and LabVIEW was still crashing when he tried to open anything project-related. In the system event viewer, there were two errors that showed up: 1) "NI Configuration Manager terminated unexpectedly", and 2) "nidevldu terminated unexpectedly" (screenshots attached below)

The solution in this case was having the customer upgrade from SP1 to SP2, and that fixed his problem. Apparently, the service pack version affected the NI Configuration Manager and the nidevldu processes.

Let me know if you resolve your problem.

Hmmm, those are indeed the two errors that show up - however, we are already running service pack 2! 
I don't know what could have changed since it was working a few days ago, maybe some file has been corrupted, and the other customer's upgrade deleted or re-installed that file?

Hi,

You can try the following as well:

- Fully un-install 'MXS' - by running installer located on LV8 CD -> Bin/Products/MXS. (If it says 'higher version is installed' try DSC 8.0 CD version instead, appears to be newer build).
- Delete the following files:

..\National Instruments\MAX\Data\*.* (All Files)
..\National Instruments\MAX\Data Fragments\niIMAQDD.mxf
..\National Instruments\MAX\nimax.ini

- Repair MAX via Control Panel
- Re-install MXS using same installer as above.
- Reboot your machine. Services should start up correctly and the LV8 Project should be running again.

Brilliant, thanks!  I didn't have the CD to hand (working from home today!), but I deleted ..\National Instruments\MAX\Data\*.* as instructed (the other files didn't appear to exist anyway) and rebooted - and it now works!  I guess something in there was corrupted or something.

Thanks very much for the quick responses!
