The Issue:

I was about to import management packs for System Center Virtual Machine Manager 2016, but the install button was grayed out? Ok, so let us do what we always has been doing, remove the already imported MP’s, but then it all gets red and error, hmm

Install button is greyed out.

Let us try to remove the already imported MPs…

All already imported MP’s have been removed, still not possible to import…

The Solution:

By removing just “Microsoft System Center Visualization Virtual Network Dashboard” it works…

Hey, it works…

It seems that this is not only true for this scenario, here is a blogpost that explains the same issue when importing the SQL MP.
