Applications no longer working after installing Catalina

I’ve just installed macOS Catalina and now none of the following work:


iMovie

Photoshop CS4

Dreamweaver CS4

Garageband

MS Powerpoint

MS Entourage

MS Messenger

MS Project Gallery

Jing


Can I get this thing backed out?

Hello there, just to confirm, some of those apps seem to be 32bit apps which are no longer supported.

I would advise you to confirm that and if possible update those apps
