I am running into the issue documented in bug id CSCtd43463 when installing 8.4.3 TSP on a 5.0(1) Unity server.
The workaround is to install Visual C++ redistribale to get msvcr80.dll in the \windows\system32 directory. The VS2005 redistributable did not install that dll on the system. I googled around and found it was in DotNet so I also installed DotNet and rebooted the server and have the DLL in the right location from those installations, but still get the error "The files AvSkinny and SelsiusNTWave.dll could not be registered" when installing 8.4(3) TSP.
The Unity server is a physical server, built using the Unity Platform Disc then server update wizard so should be good from OS side.
Does anyone know what else is needed to get this 8.4(3) TSP to install fine? I was able to update to TSP 8.3.1 fine but was trying to get current TSP version on this until Unity connection update next year sometime.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
