I guess I'm the odd one out here, but things are working for me.

I install Poser to my Program Files folder. It's a program, and that's what that folder is for.

I have UAC switched on, and it does its job for me. If I want, i can override it by using 'Run as Administrator', but I rarely need to do that.

I have one or two Python scripts myself, and they all go in the Program Files folder with the app too. No problems yet.

My content is, of course, stored elsewhere (in the recommended default location).

Issues or problems? None at all. All works fine.

Backups are easy too: I basically have two backups - C drive and Data drives. When I restore a backup of the C drive (rare, but it happens) I get all my apps back too, but no data gets overwritten.

I do install some non-UAC compatible programs to another drive, but they are few. They don't include Poser which, for me, runs nicely from Program Files.

So there :-)
