After I installed PMDG 747-400 I cant find an icon that says I can open it. I even opeend FS9 but I couldnt find anything with PMDG in it.

Hi there qwerty8956, Please sign your real name to every post per forum rules. To address your question, I'm going to assume you mean how do you fly the plane? Go to Select Aircraft, then look for Boeing-PMDG. It should be under there. 3 variants ( engine variants ). If you mean some of the documentation for the plane, go to your Start Menu, then click on All Programs, then PMDG Solutions, then you'll see the information under 747-400. Is this what you mean?

I found it now :)Justin
