I'm trying to install the lorem and mnore extension for Dreamweaver CC. I have installed the adobe extension manager cc and downloaded the lorem and more extension to my desktop, but when I click on it it dosen't install. If I click on file in the aem and try to install the extension this way, my documents window opens but the file type is a .mxp and the file type that shows is a .zxp.
So do I need to convert the .mxp to a .zxp, if so why does it download from the extension exchange site as a .mxp
Yes, you have to use Extension Manager CS6 to convert it to ZXP extension. If you don't have Extension Manager CS6 installed, you can get it from http://www.adobe.com/exchange/em_download/em6_download.html.
I think you should have downloaded it from the old Exchange Classic website. All extensions in the new Adobe Exchange are ZXP extensions.
