about the "uninstall" or "reinstall" problem
according to this
if we use Dreamweaver 2015 (windows)，it must use this tool to instead the original "Andobe extension manager"
finally I use this tool and success to install the "MySQLi Server Behaviors" .zxp file
but the teaching page seem not told us how to "uninstall" or "reinstall" the zxp file
because maybe one day the "MySQLi Server Behaviors" have a new version (I know for now is 1.0.4 but maybe 1.0.5 in the future)
so...any idea bout this ?
