can not install MySQLi Server Behaviors

Hi,
I can not install the extension MySQLi Server Behaviors.
the error message is:
this extension requires Dreamweaver 9 or higher. But I use the last version DW CC 2015). I've uninstalled and reinstalled DW, but I still have the same problem.

You need to get the latest versions of Dreamweaver CC2015 (this is different to the initial release) and you need to get the latest Extension Manager. This should fix the problem. To get the latest versions go to the desktop Creative Cloud App

You could also use the DMXZone Extension Manager http://www.dmxzone.com/go/22670/dmxzone-extension-manager-for-dreamweaver/ as a fix.

Of course I use the latest version of DW, as I told you that I've reinstalled it yesterday. Same for the Extension manager. With the Dmzone extension manager, it seems to install the extension, but at the end I don't have it.
In Windows>> extensions, I have : no extensions available
in Webassist, I have Database and then an error message with no words

the problem may be that adobe support has taken control of my machine to install the old database and bindings servers behaviors. But I've reinstalled Dw and the problem remains.

In Windows>> extensions, I have : no extensions available

I have the same despite having all of the Webassist extensions amongst many others.

The way to find out if the extension exists, go to the Databases tab, click on the plus button and you should see Dynamic MySQLi Connection as in the screen grab.

for some reason, a window has opened and with the installation of the extension
thank you

Glad it is fixed
