If you're new to the Treasures of Montezuma series, I suggest you start at the beginning by downloading the FREE first edition of the software. In this free version, you will receive six different levels, four music tracks, and a free banner. It's great because you don't need to worry about purchasing the full version until you see what else is included. I recommend that you check out the level in which you will unlock the bonus game in order to really get into the game. And yes, that level is one where you can obtain a free 'froggie'.
Once you have downloaded the free version, open it up and then take note of the name of the application - free. The Windows icon (usually on the desktop) will have the same name as well. Now, that you have this information, download the first Microsoft .NET Framework (the Microsoft Visual C++ Redistributable Package) that you can find and install it on your computer. This will help your system to recognize the application better, allowing you to run it easier and faster. Also make sure that you've got the latest version of the Microsoft Visual C++ Redistributable Package installed on your computer as well.
Open the free Windows application and go to the settings tab. After that, go to the options menu. In the next screen, click on 'Run' and enter the path to the Microsoft Visual C++ Redistributable Package that you installed previously. Do not forget to save these changes! Once you've done that, reboot your computer and start playing the game. You should notice a HUGE difference after you've done this - this is a sure way to get that bonus level up and running faster than before!
