I just installed version 2018 next to 2017, tried to install MySQLi_105.zxp using zxp installer. It says that it has installed and to restart dreamweaver (closed during install), but when I restart there is nothing happening. When I opened up a file I expected the WEbassist installer to open and for me to add a registration code, but nothing. Is this because I have both still open? The reason I do is that Creative Cloud kept sticking, so Adobe help installed from the internet rather than the creative cloud.
Spent some time with an Adobe support tech today, she tried to install the MySQLi extension manually with no success. She tried a lot of things but it would not install. Is this because I have Dreamweaver 2017 on the same machine?
