How to know if a portableapp is installed

Respectable PortableApps Forum I want to make a question:

After having installed all the apps I have noticed that one of the app that I had thought that was installed was missing. Now my question is : Is there a way to know if all the apps are installed or must I try manually every app? In practice I want to know if all the apps of this suite are installed without trying every app manually to see if it is present..

Sorry to have disturbed, thanking all that want to answer to this post, I salute all the Community.
