Please make the latest version of CC available for re-download through the Creative Cloud. With the latest changes you have basically destroyed the last feature, the SEARCH window, that was keeping me using Dreamweaver.
Adobe's version policy gives you access to the current release version + 1 major version back [N+1]. Unfortunately, if you removed your previous versions from your computer and they were older than 2020, you can no longer access them from CC desktop app.
Which version are you looking for?
You may find direct download links on ProDesign Tools' site. Be sure to follow the Very Important Instructions otherwise you'll get an "Access Denied" error.
