CS app installs add-on in CC2015 but not CC2017

[Herr Blume]

I have installed an Ajatix add-on (boughtin the  Adobe Exchange) through the desktop app, but it is only installed in DW CC2015 but not DW CC2017. uninstalled the old CC extension manager, re-booted and tried again but still the add-on is only installed in the CC2015 program.

I am in a bind because some other add-ons from S43 that I had been using in CC2015 would not install in CC2017, and I am scared to stop using CC2015 in case I can no longer update my websites if I move them to CC2017. I though the solution might be to re-build everying in CC2017 using add-ons bought through Adobe add-ons, but even that only worls in CC2015!

Question is - how can I get add-ons installed into CC2017?

Thanks for any help!

Download the Extension Manager from here https://www.dmxzone.com/go/32500/more-power-for-dmxzone-extension-manager or from here PVII Extension Manager for Adobe Creative Cloud and use either one to install the extensions.

Does the extension developer's web site have updated add-ons for CC 2017?

Thanks for this Nancy.

The developer recommended installing with their extension manager, and that did the installation in CC2017 for me.
