Works on all PDFs so far.
Seems to run faster on win7 x64 native than XP SP3 compatibility mode. However it still takes over 4 days for some PDFs on a quad-core i7.
Will there ever be a 64bit version? My rating:4

Worked on every encrypted PDF I gave it (over 20). A good buy, and the only one I found that really works (checked 4 others). My rating:5

Got the $25 version. I need to remove restrictions. It tells me the file is not encrypted, which I already knew, but does not remove the restriction - at least not in the 4 times I tried. My rating:1

After purchasing it, they only gave a link to download the program for PCs but didn't ask you if you are using MAC OR PC, What da hell????
I'm using a MAC, why would I want the PC version??

I have used this software for many years, updating it for new versions of Acrobat. I have tried several and this is the best one around. It allows me to extract pictures from or edit text in 99% of the PDFs I need to. My rating:5

The best decrypter that I have met. I didn't meet any crypted PDf file that this program couldn't solve. It worths every penny for it! My rating:5

I have been using this program since 2006 and can honestly say that it runs flawlessly. I have not come across a PDF file that this program couldn\'t decrypt. On top of that the customer service is the best I\'ve seen in a long time. I ask a question and have an answer almost immediately. All I can do is recommend this as a power user and suggest you get it too.

How do I do to run the downloaded demo guapdf from command line (Mac OsX SnowLeopard)?
After moving into decompressed guapdf dir and running the guapdf bash says it is not a known command... even not ./guapdf. Can you help?

What a joke and a fraud free demo. I tried opening a 29 thousand K document and the free demo said it made it through 51% then I tried cracking a 650K document (nearly 45 times smaller document) and the free version said it couldn't do the whole thing and could only do 53%. You do the math. THIS IS A SCAM! If you want to gain respect and trust that your product can actually crack a pdf, perhaps you should allow users to actually see that it can do so. I wont purchase unless you can prove it works. I have tried at least 10 crackers that ALL claim to be GUARANTEED and not a single one of them worked on my document My rating:1
