nimru2u.dll

[Wingman]

A .NET application that was working, now isn't. It croaks with VB complaint of 'cannot find file', but no indication of which one. However when I remove the declaration '..... As New Task' the problem goes away. I have tried uninstalling/ reinstalling with no luck.

May be related to one of the following..

  I was running legacy NiDAQ, then switched to DAQmx. At the time, the only CD I could find was 8.1

  About the time I installed 8.1, I got an error on bootup 'Application failed to start...nimru2u.dll was not found'

  Uninstalled 8.1, kind of. Got errors toward the end. Finally got clean uninstall by deleting c:\P F\National Instruments folder.

  Installed 8.6, twice. Still getting the bootup error, my application still hits same error.

Hi Wingman,

When you say you installed 8.6, are you talking about Measurement Studio or DAQ. Considering we just announced 8.6, my guess is that you are talking about DAQmx, but maybe not? Either way, that DLL is associated with our DAQmx driver and should have been installed into the <System32> directory. My guess is that you won't find this DLL in your <System32> directory. Thus what I recommend is to install DAQmx 8.8 onto your system found here. This should install all the necessary underylying components you need to run your DAQ application. As a side note, make sure to select the .NET Framework x.x Languages Support item in the DAQmx installer feature tree. This installs the .NET support you will need to run your application as well. 

Best Regards,
