  2. Save the file MatchMaker231HD.exe to any location on your computer. Do not try to run it from the website.
    (If you have SpyBot, you can ignore its warning about Bancos.Santander which is due to the way we decide what to keep from old MatchMaker versions using MMUpdate.exe. SuperAntiSpyware also has warnings, but the program has passed checks by leading detectors of spyware, other malware, and viruses, including Malwarebytes, WinZip Malware, Ad-Aware, Avast, and Microsoft Security Essentials.)

  3. Make sure MatchMaker is not running before installing any version of MatchMaker.

  4. Uninstall any previous version of MatchMaker. Read the details here if you are unsure how to do this or you have edited the descriptions or added species or illustrations in a previous version. If you skip the Uninstall procedure, the program will probably work anyway, but stray leftover files can cause problems sometimes.

  5. Double Click on MatchMaker231HD.exe first (it might be called MatchMaker231HD) and installation will proceed.

  6. You may be asked if you want to allow a program from an unknown publisher to make changes to my computer. Choose Yes.

  7. On some Windows 8 systems, you may have to adjust Windows' Compatibility Settings to "Windows XP (Service Pack 3)".

  • This is a large file that would fill most of a CD. Downloading could take as little as a few minutes, but it may take more than 20 minutes, even with high speed access. If you are unable to download the file, you can obtain a free Version 2.3.1 CD by mail.

  • You can install the program to a different application folder from the default location for applications. When installation starts, after you click Next, you will see the standard location.
    C:\Program Files (x86)\Matchmaker
    If you wish, change this to another location.

  • You can install the data to a different folder from the default location for program data. (The default location varies with the version of Windows, but once you have installed MatchMaker you can find the location by choosing Data Location on the Advanced menu.) If you want to install to a different folder, a file called dataloc.txt must contain the new address of the data for the program to run properly. You make a file dataloc.txt containing the correct data folder address on one line, for example
    Using a text editor like Notepad, save it to a known location, then copy it into the same folder as MatchMaker.exe.
    (for instance C:\Program Files (x86)\MatchMaker\).
