Yes I do have the correct version installed, i use it for the mouse/keyboard function, and viewing video clips while away from home. I've uninstalled the app (i.e. no smartglass apps installed) and in IE menu chose Share Page > Xbox and it sends me to the store to install smartglass for xbox 360. I installed the 360 app which as expected won't connect to my xbox one, I've installed both apps and it still launches the 360 version.
If anyone doesn't have smartglass installed, can you try using the Share Page > Xbox option in IE? Do you even see the xbox listed as a share option? If you click it does it send you to the store to install the smartglass for xbox 360? Does this work for anyone with the smartglass for xbox one app?
