Your question doesn't make sense. The 'original' Premiere is well over two decades old, is no longer being sold, and probably wouldn't run on your system anyway.
Not what I mean.
Like when you first download premiere, I am missing specific windows that I had before.
Like to view and edit the video in a panel.
Sorry for not being clear.
Got it now. You're looking to Reset the Workspace.
Premiere Pro is very complex software meant for trained professionals. Don't skip reading the manual.
Thank you so much.
