User adol77@gmail.com wrote about ver. 3.1 2010-08-26 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?

User Dan wrote about ver. 3.1 2009-11-14 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

User Peter wrote about ver. 3.1 2009-10-28 Just excellent. Demo version was crap. Full version excellent. Why not deliver a limited time full demo version...
User Ber wrote about ver. 3.1 2009-10-23 1. Demo version is useless.
2. Full version is excellent.
3. How to get command line version? I sent 4 emails -- got no reply.

User jamie wrote about ver. 3.1 2009-09-25 Only one key because of the absurdly slow method of delivery via ShareIt. 'Your software well be delivered between 4 and 24 hours' is not acceptable for a product download. My rating:1
