Installed and registered with problems (turns to unregistered after successful activation, finally way activated) on a Win 8.1.2 Pro 64 bit system.

A company without name and address: Passcovery Co. Ltd. released its first high-speed, professional software solutions for recovering lost passwords in 1999. Today, the company's software is successfully used by law enforcement, government agencies, corporations and private individuals around the world.

Hmm, what should I say?

A small resizable window opens, you select your .ZIP file (recognizes only ZIP) and start cracking...

And now comes the nice thing: the program tells you (in my case), that it would need an "estimated time" to crack the password of 1:27 h:m. That's good. It is the first time in my life that a password cracker gives me an estimated time. I would have expected something like 1.3 billion years or 800.000 years if you use parallel computing with a 1.000 PC cluster or something like this.

It tells me after opening a file, that the maximum supported password length is 63 (roughly estimated: more passwords than molecules in the universe...)

Brute force or mask supported brute force does not make sense on longer passwords.

The only method with a certain chance really to crack a password is the "dictionary" attack. But this program does not deliver large dictionaries, nor gives it links or hints where to download the big ones.

In my test case the password cracking speed is about 100.000 passwords per second. No, it will not finish in about hour. Or maybe yes? Finishing and telling me, that I need more time.

No, the program is fair, really! It tells me that a key with 12 digits, only Latin small&big characters will need roughly about 131 million years, days not counted, with a cracking speed of 100.000 per second. Increasing this speed by 1000 would reduce the time to some lousy hundredthousand years... : It is not only the time needed, thing of your energy bill 1 million years later. Incredible!

Use it, if you play lotto. If you don't play lotto, than you know, that you will not crack anything but Mom, Dad, Sweetie, Test or Master.

Uninstalled via reboot.

This is the BASIC version of the software and does not support GPU, even though the product description on GAOTD says that it does.
Misleading and deceptive.

Installed and registered without any problems, decided to a do quick test using the old (weak) zip method of encryption.
When attempting to open the above file on clicking on My Computer a blank window appeared, no drives listed!
Found a way around this and managed to open my test file. Found very simple four upper case letter password immediately, on a second test with a simple seven letter upper case password claimed it would take 10 min at around 70,000 passwords per second.
When it did present the answer it kept telling me I could upgrade to something useful, that is one using the GPU, the basic addition being purely a stepping stone for sales to more expensive programs.

Many years ago I needed to crack the password in a zip file encrypted with the old method, there was one sure way of doing this if you had the right password cracker.
The old system had a very basic flaw in that if you knew the contents of one file it could work out the three keys needed to extract the information and fortunately it contained an EULA and I knew the contents, it still took minutes, but it worked.

Off topic.
Recently a level of unpleasantness has begun to permeate this site; people offering/requesting help have been heavily marked down, yesterday for example one comment resulted in 21 No votes.
If we lose these types of comments the value of this site will be diminished; may I request that this petty mindedness is discontinued and instead you have the guts to post a comment.
Personally I have found this site very useful in that it has helped me when I have encountered problems, please a little courtesy!

@ Edgar #5

Not to discuss about "vulnerabilities". A TrueCrypt file with a longer password still cannot be cracked.
