Installing Program Brings Up This Notice

Doing a re-install of Flight Simulator X and get this notice at beginning of installation:

1: Allusers property is not 1-this MSM cannot be used for a per-user or fallback to-per-user installation.

I have no idea what this means. Everything I found on Google seems to be oriented to specific programs. Can anyone help? Thanks.
