I was installing both EXE's in an elevated window as another user. I have elevated and "mortal" accounts. I normally use the elevated for running installs. When I do not elevate, the apps install and appear to coexist without taking a dump on my desktop.
For an app that is largely targeted for enterprise use, I'd have thought they would have tested for this.
I'll leave this here for the next poor soul that assumes that the app will install properly in an elevated context.
