.NET framework prerequisite for wyBuild installation

We are trying to install wyBuild on a windows server 2012R2 machine where .NET framework 4.7.1 is installed.

When trying to launch wyBuild software after installation, it tries to enable .NET framework 3.5 which is not available by default on the machine and we are forced to install the same even if 4.7.1 is installed.

Is it mandatory to have .NET framework 3.5 even if .NET 4.7.1 is installed on the machine?

Have you choosed the right version of the library?

wyBuild requires .NET 2.0 (or 3.5).

wyUpdate you have the choice of .NET 2.0-3.5 OR 4.x
