There are two directories in the zip file, Multisamples and Programs. Each has a subdirectory that needs to be installed. The multisamples 64bit default location is "C:\Program Files\Cakewalk\Dimension Pro\Multisamples" and the programs go into "C:\ProgramData\Cakewalk\Dimension Pro\Programs".
The C:\ProgramData directory is a hidden directory. Let me know if you have any trouble. I would have posted earlier about the DSF examples (I found them a few days ago poking around their site after receiving an email from them) but thought the issue was resolved.
