Cannot install on CC

I have been trying to get Design Extender, and data assist installed for Dreamweaver CC. Every time I try to get them installed I receive this error (see attachment). I have installed the deprecated_serverBehavior extension located in the Dreamweaver disabled features folder. What can I do to get this installed and back on track.

when you download the extension files, make sure you are downloading the ZXP version.

when you click the download link, you may have the option to open the extension or save, make sure to select the option to save it.

once the download completes, open the extension manager and click the install button, then browse to the downloaded ZXP file.

Thanks Jason I have done this a number of times. I have opened and tried that way and have also downloaded and then opened from install link on top right of extension manager. I still receive the same error...

try recreating the users configuration folder:

I am not seeing how to do this for the Dreamweaver CC.?

it's the same as all the other version.

when you get to the Adobe/ folder, there will be a folder for the dreamweaver version you have.

in your case, named Dreamweaver CC

Ok, did this and it still is giving same error.

I found out how to get the issue to resolve. There were some old files still on the computer from other versions. So I removed them and that took care of it. Thanks!
