ABB SLP Distributor not installable for .NET Framework 4.6?

JoonaKorpinen Switzerland
Hello there!
I'm quite new to this Forum and not sure if this is the right place to put this, but here goes:
When I attempt to install the ABB SLP Distributor software on our server, which runs on
.NET Framework 4.6, I get the following error message:

We need to use a network licence, so that all our students can work with Robotstudio in different locations.
Is it possible to get the SLP Distributor to work on the .NET Framework 4.6 or do we have to actually downgrade
the Framework on our server?

I really hope someone can help me out with this and thanks alot in advance  B)
