When attempting to reinstall Adobe Extension Manager for Dreamweaver CS-5 a window comes up and gives the following message: The Extension Manager will now launch and finish updating Dreamweaver.  A second window opens saying: You are about to install the 'Dreamweaver HTML5 Pack' extension.  Please read the following carefully before you continue. (Extension Disclaimer) Accept or Decline?  I Accept, and then move on to the next window.  The following messages comes up: The extension 'Dreamweaver HTML5 Pack' does not contain valid signature.  The extension will not be installed.

 

Is there a fix for this?  I have uninstalled Dreamweaver, downloaded the file from the Adobe web site and reinstalled about 5 times, all to no effect with reference to the above issue.

 

It was working perfectly before I had a hard crash.  I then replaced two hard drives and reinstalled all my software.  This has been an issue with Dreamweaver since reinstalling it after the crash.  Does anyone have a solution to this problem?

There are two main reasons why Dreamweaver is losing out. One is Server Behaviours and the other is the ability to extend the program using the Extension Manager. Now you are also stuck with the fact that Adobe has turned its back on anything that has nothing to do with CC.

 

DMXzone has come to the rescue with

Try that and all should be well.
