Default Forgot the Basics

I have been away from my gear watch for two months and I forgot how to do some of the basics I did before. I know how to use Odin to flash over the files for the new firmware for the gear watch itself. . But there is a Gear Manager update that has to be installed separately. The GR Manager update has been available for a week and it is posted in this forum. It has to be installed on the phone separately from ODIN. I simply forgot the process for installing the Gear Manager software. SInce I have a rooted phone I have done this before, but since I have been away from the watch for months I forgot.

Can someone remind me of the process for loading or installing the Gear Manager software onto the phone itself. I can't automatically do it thru the software itself because I have a rooted phone with Null custom rom
