RVM Integrator is not just an integrator. It's main purpose is to actually slipstream hotfixes and third party utilities into your Windows install disks. Integrating is simply a way to attatch setup files into your windows disk and have them install at a specific moment during Windows setup. Slipstreaming will actually overwrite older files and place itself directly into the windows installation.
Fixed: (v1.5.1) Recompress UpdatePack/Addons plugin was giving an error during compression of certain addons.
