Pure Virtual Function Call error

[PauloM]

Hello,

I´m running a Labview exe with NI DAQ 7.4 and it´s working fine.

the problem happens when I shutdown the computer. An error appears on the screen saying that nipalsm.exe has closed and commited a pure virtual error.

I press OK and the system shutsdown normally. This error doesn't occur all the time, it's random.

Can anybody help with this??

Thanks you,

Paulo

Hi Marc,

I read the links you sent me and it seems to me that those guys don't have exactly the same problem as I do.

My error is not popping up after the installation of the drivers, it is happening randomly when I shutdown my PC after using LabVIEW. Another difference is that on my error description I read "Pure Virtual Function Call error" and it seems to me that the other guys didn't have this.

By the way, what's the purpose of the NI-PAL driver? Can I uninstall it? What will not work then?

Do you have any other clues?

Thanks for your answer,

Paulo

Paulo,

The nipalsm (NI-PAL service manager) is running a different driver related service for NI-DAQ, NI-DMM, and so forth.
All that the "pure virtual function call" error means is that a null function pointer has been invoked, or that code has been overwritten to branch to memory address 0x00000000. This typically occurs due to memory corruption.

Then I advice you to repair your LabVIEW run-time, MAX and DAQ drivers and it should solve your problem. The last solution would be to uninstall all softwares and install them back. Eventually if you use DAQmx drivers you can upgrade them.
