A simple installation and registration, on opening a simple interface was presented.

Using a hex editor modified today's download zip file by modifying the names of the file it contains at the end of the compressed archive.
Attempted recovery was unsuccessful even though it claimed had recovered the files.

Using another copy of today's download modified the characters PK, that appear at the front of every zip file, to MZP typical of EXE files and DLL files.
Yet again it claimed a successful recovery but actually recovered nothing.

It was so unsuccessful that I was concerned that I was doing something wrong and so tried a number of times without success.

Been using compression programs for just short of 30 years and never needed to recover one.
If I was concerned about corruption of archives I would use RAR files where with slightly less than optimum compression they can be saved with a built-in recovery system.

Munsoft have a couple of problems with this program and others of their data recovery range, either they have left the products to stagnate since their first giveaway of their easy data recovery suite which includes this program in this version back in 2013 or they don't use any formal versioning system by which we or even they can intelligently suggest that we should download the latest build.

I don't have any classicly broken zip files to test this on so cannot confirm XP-mans findings the usual breakage is loss of the last data chunk in a multi-email/newsgroup message posted zip archive of many files, with the loss of the final section the zip archives master directory which is at the end of zip archive is lost and normal zip extraction refers to that when displaying the zip file contents index. The primary repair technique is to sequentially read the remainder zip file and rebuild a master index of the files that remain by using the per-file zip headers that prepend each file in the broken archive. That way normally all of the individually complete entries can be recovered and extracted out of a damaged normal zip archive. I would normally fish out the original PKzipfix.exe commandline program to do that job, but not done that in years!

The reason I obliterated the names at the end of the ZIP file was to test if it could by some means work out what files were contained in the archive. It was a real surprise that it was so unsuccessful as I anticipated it would perform somewhat as you describe in your comment.
Failing my second test was a real eye-opener, changes only to the first three bytes of the ZIP file and couldn't recover it, and this from a $60 program is just hard to believe.

I didn't have any broken ZIP.
So i made 4 ZIP from a series of photo's i used yesterday.
2 of them are protected with a password(gotd).

And these 4 zip's i have manipulated with a hexeditor. Not very much: something just altered the name of the original file. Another somewhere else in the zip altered 10 bytes to 0123456789.

The GOTD program has great difficulties with the password protected files: all the result-files has 0 bytes.
And the other unprotected files: the result were soso:

The original was:

Damaged ZIP:

Difference made with a hexedit program:
