Re : .net constructor error message

[Gary_H]

Hi,

I'm trying to use the .Net Constructor node with an assembly which I'm sure has been used by others,

see http://forums.ni.com/t5/LabVIEW/TI-USB-to-GPIO-interface-EVM-adapter-Dll-for-Labview-driver/td-p/112... for example.

But when I try to create an object from the assembly I get the following error displayed in Labview:

I don't understand why I am prevented from creating an object instance ?

I'm using : Windows 7 Pro, Labview 2014 SP1. And Microsoft .Net Framework 4.5.2 is installed.

I've attached a copy of the USB Adapter Driver assembly, (replace file extension: .z with .dll to use.)

Thanks,

Gary.

Jean-Marc,

Thank you for your helpful answer, problem now resolved.

Here's some additional text to the link text you pointed to:

The link text said:

Tip: In Windows 7 or later, you also can right-click the assembly and click Unblock on the General tab to grant an assembly full trust.

When the .Net assembly file was right clicked in Windows ExpIorer I saw:

Clicking on "Unblock"  resolved the problem and allowed the Labview .Net Constructor node to function correctly.

Thank you Jean-Marc.

Gary.
