Have just upgraded HTML Editor v3.3 to v3.4.0 and cannot get it to install in D'Weaver CS6. After installing the extension in the normal fashion and then opening a web page in D'Weaver the install dialogue for ADV HTML Editor displays and when clicking to install the extension an error message shows. " When executing 'Onload' command a Javascript error encountered in 'install.htm' ie. "dmxAdvHTMLEdit30_install" : initUI is not defined.
Running Dreamweaver CS6 in windows 7 SP1
Cannot get past this point as error window just refreshes with same message. Had no probs with previous version. Any suggestions??

Please clear your Dreamweaver cache: www.dmxzone.com/go/16740/clearing-dreamweaver-s-cache/

Thanks ! Followed your instructions and issue now resolved - v3.4 now up and running.
