Cannot uninstall extensions in Dreamweaver CC 2014
I have Dreamweaver CC 2014 and Adobe Extension Manager CC installed. When I open Extension Manager there are no extensions installed for Dreamweaver. When I try to install WebAssist Data Bridge I get this message. I get a similar message when trying to install eCart
The extension you are about to install conflicts with the following extensions. Do you want to remove the following extension and continue installing?
The extension'Data Bridge' installed in the product 'Dreamweaver CC 2014'
When I press 'Yes" I get this message. Error occurred. Eroor code is -451. The extension wil not be installed.
I have unistalled and reinstalled Extension Manager and Dreamweaver several times. Originally there was an extension in Dreamweaver for server behaviors, now that is gone. I do not have a clue where to go from here. Any ideas?
