This is a self extracting 7-Zip archive containing the Library and Styles content for Adobe Encore CS5. If you downloaded the trial of the CS5 products from Adobe's website you will be missing these items and unless you purchase the product you won't be able to download these content packs straight from Adobe. Hopefully this will solve that problem.

Installation is as simple as a copy and paste to the correct folder. Instructions are included in the download. I have tested these on Adobe CS5 Master Collection on Windows 7 HP x64. You should also be able to install this on the MAC version just as easily. I've included instructions for MAC and Windows but I have not tested the install on a MAC computer.
