The install log shows
 
It seems that DNN5 module's manifest included in the PA you used references an old 3rd part library which is no more used in this version.
Did you finally managed to install it on your DotNetNuke ? If not, could you edit the file "Aricie.PageFlip.dnn5" in the PA you downloaded, remove the element which references "itextsharp.dll" and try again to install the corrected PA ?
Otherwise, we planned to release a new version of Aricie PageFlip this week.

downloaded the patch version from snowcovered and it worked correctly.
unfortunatley the patched version is the 64bit version i think and causing problems when i try to upload a pdf.
