Cannot find a valid editor for this file extension

Question

I changed Extensions.txt to

Program Files (x86)\Adobe\Adobe Dreamweaver CS5.5\Configuration 

And I changed MMDocumentTypes.xml to

 Program Files (x86)\Adobe\Adobe Dreamweaver CS5.5\Configuration\Document Types 

But I still get "Can't find a valid editor for this file extension."

Dreamweaver configuration works with user folder priority. Typically, at least one of the files you mentioned has copies in the user configuration folder. Therefore, if they are present, they will not be used in the application configuration folder.

Adobe's technical product, which describes how to add file extensions ( http://kb2.adobe.com/cps/164/tn_16410.html ), lists the user configuration folder under the changes in the extensions. txt file. In addition, while Technotech states that you are editing the MMDocumentTypes.xml file in the application folder, make sure that you do not have a copy in the user folder. There are some circumstances where there will be a copy in the user’s folder, and if so, you should make changes to the copy of the user’s configuration folder, not the version of the application’s configuration folder.
