Unexpected error in MAX when exporting hardware configuration

[Ransu]

Trying to export hardware configuration in MAX results in an unexpected error (log and dump attached).

I've just upgraded from LV8.6 -> 9 and also updated MAX 4.5->4.6 and DAQmx from 8.6->8.9

This has messed up a number of things, including my DAQmx tasks...

Now uninstalling and reinstalling doesnt help and reverting to the old version seems to require you to revert everything to an older version (ie. back to LV8.6)...

Not fun 😞

Timeline:

Open MAX 4.6.2f1
Export... -> Configuration Export Wizard
Export My System
to .nce (or anything else)

(List shows NI-DAQ 8.9 even when its uninstalled)

Trying to export to a "NI-DAQmx UTF-8 INI File"

shows no NI-DAQmx Tasks : "<no exportable data>"

Then you click anything (like select all) and: "Unexpected Error"

"The NI-DAQmx plug-in caused an exception in the CpcCopierProxy::GetSourceItemsIfNecessary function in the NIMax process."

the story continues...

I've now installed DAQmx 9.02 and now the export shows all my tasks just fine. Everything seems ok.

However when I press 'Export' I get:

"Another process has changed or deleted some items while this wizard was open. Unable to perform the requested copy operation. Please restart the wizard and try the operation again"

I get this error whatever combination I choose...

While back I had similar problems with MAX and there was some file you needed to delete to get it to 'refresh' itself... ?

Any word on the cause of this error? I am getting the same error.

LV 2009

MAX 4.6.2f1

A fellow victim! Hey, nothing new here. I'm just about to uninstall EVERYTHING on the machine and then reinstall - I will probably lose my MAX-settings, DAQ-tasks and have to rebuilt them all by hand ... oh well, at least I learned NOT to try to update my machine when I have an ongoing project ... should've reserved a separate machine for LV2009 and tested everything first...

I have tried to export MAX settings from 3 machines. Two of them have been successful with various versions of LV and MAX etc. The machine that it does not work on is the only machine with the NI 6224 PCI card.

Perhaps there is some kind of windows pooling of the card or something that is interfering with the export??

I also have a NI-6225 on the machine, for which the DAQmx Tasks I have configured with LV8.6 are for and would like to export.

I have now uninstalled everything on the machine - even deleted Local/National Instruments under profiles ... basically cleaned the machine of everything to do with NI - then installed in order -> LV2009 4th Q -> DAQmx 9.0.1  ->  Drivers (MAX 4.6.1f) ...

Then rebuilt all my tasks again with the new version of MAX ... relinked them all to my project ... everything by hand

Now export works again. Sorry didn't have time to start troubleshooting the cause of the problem any longer...

Thanks for the info.

I guess I will have to to that as well. When you deleted Local/National Instruments under profiles, how did you go about that?

I have tried to uninstall everything and reinstall though I will also try your instalation order, however I always seem to retain the previous tasks. Could you help me out and clarify what you had to remove beyond the windows controll panel uninstall.

[Ransu]

Ah, not under local but application data...

C:\Documents and Settings\All Users\Application Data\National Instruments

You should find the following folders:

Assistants
CVI90
Distributed System Manager
Installation Logs
IVI
License Manager
LVProductDLLInfo
MAX
MDF
NIvisa
rts2cdf
SEProductDLLInfo
Shared
Shared Memory
Trace Logs
Web Services
Web Services 2009 32-bit

I just deleted them all (since I had such a mess of versions and updates all from 7 to 9 installed on the same machine)

You could try deleting just the MAX at first and see if that helps...

Thank you for your time to respond to my questions!

I tried to uninstall and delete other folders with no luck. However, I was able to clear the export issue from within MAX, Tools->NI-DAQmx Configuration->Reset NI-DAQmx Configuration.

I still have to recreate my tasks but better than not being able to export them for application distribution.
