Programming Nidaq in Visual C# .NET

[juergen1a]

Hi,

I have a Problem using Nidaq-DLLs within my application

on a network drive.

Calling my application on a local directory, everything works fine,

but from  a network drive I get the following error:

************** Exception Text **************
System.IO.FileLoadException: Could not load file or assembly 'NationalInstruments.DAQmx, Version=8.7.20.11, Culture=neutral, PublicKeyToken=4544464cdeaab541' or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT: 0x80131417)

   at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

It seems that I don´t have the permisson to call a Function from the DLL.

What can I do?
