nipalu.dll error upon loading .vi

[Markusw116]

Hello together,

Today when loading a Labview-Routine in LV2011 I recieved an error message telling me that a NIPALU.dll was not found.

The strange thing is that the program was running without any proplems in the past. So today until I had to restart the PC. After the reboot and trying to open the vi as usual, the above mentioned error occured. Restarting once more did not ressolve the problem... Inside the .vi files belonging to the routine, modules connected to a C-DAQ chassis are read out, a c++ subroutine (as .dll) is executed and only very basic functions are beeing executed.

I am now removing the labview version and installing the newest (LV2013 Fall) with the newest set of device drivers, but does anybody have an idea where this error could have come from and why? As I wrote, everything was fine and the program running as usual, retrieving data from the CDAQ modules and displaying the values, und then suddenly I permantently recieve this error after restarting the PC...

From what I found and read about this topic I found nothing that really could explain to me why and what caused that problem, so amy very thankful for any help and advice.

Thanks very much ahead!

Markus

Hye 

this is the same for me! Someone could help us?

Same thing. For all I know, this was caused by my Avast antivirus detecting it as a risk and "taking care of it". I don't know what exactly happened, did it delete it or just some sort of guarantine, I can still find a nipalu.dll on my system32 folder—wrong one perhaps?

Yep, it was deleted from the SysWOW64 folder. I copied it from another PC, solved the problem.

ah, ok - there's a similarity. I use avast antivirus as well, so that might be the source of the problem. So what did you do exactly? you restored the NIPALU.dll and checked it in Avast AV as safe..?

Thanks!

I got the same thing yesterday.

Avast was detecting a thread for that dll, and deleted the file.

This happend while trying to open a VI with IMAQdx functions. (A VI from the forum)

Was not able to restore the file from Avast, had to get the dll from another PC.

That's it. I added SysWOW64/nipalu.dll as an exclusion and restored it by copying it from another PC.
