You can install and use differing versions of SketchUp on a computer. You can not install both the 32-bit and 64-bit version of SketchUp 2015. So if you are using a version earlier than 2015, you can install 2015 64-bit without affecting your current version.
My desktop is 64 bit but laptop 32 both Windows 7. I use desktop mostly and laptop to show customers at the job. Can I install 64 at home and 32 on laptop without any sharing issues? Any benefits? Is that even an option when I purchase Pro for my 2 computers?
