What the above program does is enable you to convert to MS Word or Rich Text Formats (RTF) so that you can edit, then convert back again into PDF. You could try it, but if you have any PDF formatting set-up you will lose it in the conversion. But Adobe Reader allows you to copy to Clipboard anyway so I don't see what value that program actually provides.
Editing in Acrobat is one of the features that Adobe jealously guards for itself - it wouldn't sell any copis of Acrobat if it allowed this for free.
