How to consistently open application (Adobe Acrobat) with the same UI?

What exactly are you trying to do? The best way is not to use GUI automation if you can avoid it somehow (e.g. using PDF activities instead).

This is generally a very difficult problem when creating attended automations. I don’t think you can tell Acrobat how to configure its UI, so the only way I know to deal with it if you have to use GUI automation is to make the process robust to the different variants using Pick, Check App State, etc.
