[michelinnova]

Hi,

I am using Visual Studio 2019 PRO with Measurement Studio 2019 and the version 4.8 of .NET Framework.

I reference the library NationalInstrument.Common with version 19.1.40 and my program apear the error of the images.

In my program I remove all references of code of the version of the images beacause i use the new version because my program is a migration.

I don't understand why the same error keeps appearing. The error library is neither referenced nor named in the code.

Please I need help. Thank you!
