An SVG file is a vector graphics file, not a program.
It sounds like you wish to install an extension that will import SVG image files.
There is a very old one, and it may not work in current SketchUp versions. (it is not properly wrapped up as a SketchUp extension.)
Trimble’s Extension Warehouse has no SVG importer extensions.
This post says you can open the SVG in Inkscape, export it as DXF.
Then use one of the DXF importer extensions or SketchUp Pro’s native DXF importer.
I don’t know what this means.
