Is that giving you any error message ?
No error message when trying to search for updates through CC desktop app. It just says it is the up to date on 2015.0. In Photostop-> Help, the Update selection is grayed out as well.
When I try to manually patch it using the direct file, it gives me an error: "Update Failed - Update could not be applied, Please contact your Administrator if you want to apply update on your machine. Updates have been suppressed by the Administrator."
Try from creative cloud app.
You mean install Photoshop from the Creative Cloud Desktop app? That is how I originally tried to install it and it did not work; it will not detect the 2015.1 update.
