Adobe Extension Manager for Dreamweaver CS-5
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?
