Error loading lvdaq.dll

[User32654823]

Hello together,

I use Labview 2009 SP1.

Most time when i load my Labview project i get the error message: "Error loading lvdaq.dll , A dynamic link library (DLL) initialisation routine failed."

But when I reboot the machine enough times it starts to work. But some minutes or hours later, its possible that it doesnt work again when i open another project.

The solution to reinstall DAQmx doesn't helped for me, i tried it so much...without an positive effect. And I reinstalled Labview too...

MAX has also a problem, there are no DAQ devices in the list.

I'm admin on my PC and I have administrative rights for the NI folder.

So are there any other solutions for me? Thank you!

That dll is part of traditional DAQ, not DAQmx. What OS are you using? What DAQ cards? What LabVIEW DAQ functions?

Thank you for your answer.

Oh...traditional DAQ, I tought it's DAQmx. Ok then i try to reinstall T-DAQ also.

I use Win XP.

I have an old card, PCI-6025E, but i want to upgrade our system with a PXI system soon.

I have to look which DAQ functions are used.

Thanks for the link, but this doesn't help me.

Because T-DAQ is already installed on my computer (i installed it more than one time)

But now i know it is a problem with T-DAQ and not DAQmx. But DAQmx is also corrupt, because MAX doesn't show the DAQmx components.

If you look at this site http://zone.ni.com/devzone/cda/tut/p/id/6910 it looks like your card is supported by DAQ-MX 9.02. But you should give your locale NI office a call and hear with them just in case.
