Permissions after installing compiled app

This might not be an issue with RInno but an issue with my knowledge of Windows permissions. When I create my app with privilege = "admin", you need to be wary of how you install it. Here are some scenarios and how they played out for me:

- double click on app, install to default location C:\Program Files. The app will not run, it complains about permissions regarding WSF.
- double click on app, install to C drive. No permission errors.
- right click and install as administrator to C:\Program Files. No permission errors.

Setting privilege to lowest was also "weird" with it's permissions.
