User Andy J wrote about ver. 3.2 2011-10-24 Good simple to use... The 3.2 Demo didn't work as well as the full version.
Demo had garbled bookmarks and 1 page only to test program. My rating:4
User Ratty wrote about ver. 3.2 2011-10-19 Removed printing restrictions in less than 5 secs. V happy :)
Now i don't have to have a laptop to read my notes... My rating:5
User Mike wrote about ver. 3.1 2011-09-14 Very simple, straightforward, and reliable program. Works every time.
User wrote about ver. 3.1 2011-08-06 Outstanding support. I had a problem removing restrictions which was fixed within 15 min after my first email. I bought my first version of GuaPDF in 2002 and it has helped me many times for removing restrictions (for copying text from PDFs).
User Joey wrote about ver. 3.1 2011-05-11 Removing restrictions: works.
Decrypting: Doesn\'t work (normal 128 bit AES encryption (Adobe Reader 7 and above)), therefore useless for this purpose
User Keith wrote about ver. 3.1 2011-02-09 We had an employee encrypt a file, and take the key with them. This unlocked the file for us instantly. Just as advertised. Brilliant ! My rating:5
Author david hawke wrote about ver. 3.1 2011-01-29 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
User Tom the Toolman wrote about ver. 3.1 2011-01-26 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
User Harvey Lewis wrote about ver. 3.1 2011-01-05 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
User Mitjulia wrote about ver. 3.1 2010-12-25 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??
