I follow the instructions to start the agent on my Windows Server 2019 machine. This works correctly, but I am then unable to install it as a service (File / install as a service from the agent window). When I select this from the agent window I get a dialog:

It also prints a stacktrace:

So my questions:

1) Do I interpret the stack correctly that it's looking for .net Framework 3.5? That doesn't exist by default on Windows Server 2019 (which has 4.7). If so, the dialog message is misleading.

2) This is a bit inconvenient if so, as I'm in a corporate environment and don't have the rights to install this feature myself. Might be good if this dependency was documented and preferably removed...
