I was able to install MobileSheets Companion on an old Windows XP laptop. When I launch though, it says
(null) is not a valid Win32 application

The companion app does not support Windows XP. It only supports Windows 7 SP3 and higher. Windows XP support was dropped a long time ago due to a need to update some of the dependencies of the application. I've updated the companion application website to reflect this.
