Chess Openings Wizard – Program Status

“Before you read the bug report…”

Chess Openings Wizard 2016 is constantly under development to stay current with new engines, best practices, new versions of Windows and the great ideas from those who use it every day.

That said, it is risky to make the bug list available to the public. The vast majority of software publishers keep their bug list private so as not to discourage new purchases who might assume that the software has too many problems because everything known about the program is in this list.

Rest assured, Chess Openings Wizard is used by more than 60,000 chess players.

I publish our bug list because:

I personally appreciate it when a software maker tells me about any known problems for programs that I want to purchase.

I think chess players are smart enough to realize that all sophisticated software has bugs, and that listing them publicly is my way of making sure you know it’s being worked on.

The most recent builds of Professional and Express contain these changes:

  1. When you purchase a new program, your permanent product key will be emailed immediately. (All previous owners got an email in 2009 with their product key.)
  2. You can install your product key on up to three of your computers. (Please don’t share your key.)
  3. The registration system does not require a connection to the internet.
  4. The program does not warn you of updates. Installing updates is still a good idea, of course, when they become available.
  5. You can log in and get the latest download links and your product keys any time.

Chess Openings Wizard Professional does not offer a trial version.

Owners of all registered versions get an email with their registration keys and download links for the new programs.

The Lite version has been phased out. The Express trial version replaces the Lite version. After the Express version’s trial period expires, the program is still more powerful than the old Lite version.

Note: The Express version has not yet been upgraded to the 2016 level.
