Hi, @David Zemdegs
Thank you for posting in Microsoft Q&A forum.
The "serviceconnectiontool error prereqs for this tool do not seem to be satisfied" error message indicates that the prerequisites for the Service Connection Tool are not met.
According to Microsoft documentation, the prerequisites for the Service Connection Tool include having a service connection point configured for an offline, on-demand connection, running the tool from a command prompt as an administrator, having both the Visual C++ Redistributable x86 and x64 files installed, and having .NET version 4.6.2 or later installed.
Please ensure that these prerequisites are met before running the tool again.
