Most of the better ones will self install and give you the option where you want them to install.

Others may not. With VST's that install a DLL file.... just remember the location of the installed file and move it to a folder for DLL files. In the DAW, you tell it where the file folder is located and you should be good.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
