First, go to https://store.chessclub.com/downloadable/customer/products/ and download your purchased copy of the Komodo chess engine.
Depending on your web browser, you will be asked to Open or Save it, or it will automatically download to your default download location. If you are asked, select "Save File". This file is zipped (compressed). Thus, once saved, right-click on the file that starts komodo-tcec-........zip to Extract the contents.
Extract the files into a Folder, for example My Documents. NOTE: ICC recommends the below locations if you also plan to use Dasher, ICC for Windows or other ICC interfaces:
If you have a 64 bit machine: %PROGRAMFILES(X86)%\Common Files\Internet Chess Club\Engines\
If you have a 32 bit machine: %PROGRAMFILES%\Common Files\Internet Chess Club\Engines\
Once extracted, Open Blitzin and select “Edit -> Settings -> Engine/DGT" from the top menu. You should see a UCI Engine configuration screen.
Click Browse and navigate to where you extracted the files and select the 32 bit or 64 bit version of the engine.
Now click OK on the configuration page and your new engine is ready to use.
