Edit: I just noticed that there is another Klondike thread on this forum (go to the "Similar Threads" section below). This thread gives some more background to the version / freeware issue of Klondike Pro. I myself have discovered Klondike Pro only today and played a couple of hands of version 2.5 without any problems.
My comment below may still be interesting - at least for people who don't know how to run Klondike Pro.

Original Comment:

It would be nice if the reviewer updated his / her game description. I followed the link to the homepage of Klondike Pro and saw that the version is 2.5 and appears to be an enhanced and complete freeware version (compared with 2.1).

Further, if you download and install the zip file there, you can't simply run the application. It uses Dosbox via a bat file (start2.bat) and a config file (dosbox.con), and you have to edit both files to point to your installation directory (using Notepad, for example).
More precisely: You have to replace the default c:\KPro_253 by your own installation directory, once in each of the two files (or you install to c:\KPro_253, then you can start Klondike Pro using start2.bat as is).

One more observation: Klondike Pro uses Dosbox 0.72, but should work with 0.74 without a problem (but possibly without any noticeable advantage :-)).

Have fun!
