1. In Windows Vista you may encounter extra warnings for security reasons. If User Account Control is enabled (as it is by default when Vista is installed), you will be warned first at each stage of installation, "An unidentified program wants access to your computer. Do not run the program unless you know where it's from or you've used it before." Click Allow in each case.

2. If you have downloaded the files from the internet to install to your Hard Drive, setup normally proceeds automatically when you run the file MatchMaker20HD.exe to unzip the files. (While the default drive is C:\, you can change this throughout installation if your programs are on a different drive.)

3. Once you have started the setup program you basically have to okay a number of steps. There is a message "Welcome to the MatchMaker installation program. Setup cannot install system files or update shared files if they are in use. Before proceeding, we recommend that you close any applications you may be running." Click OK. Next comes "Begin the installation by clicking the button below". Click the button. Next comes a window saying the setup is "Checking for necessary files". Wait for it to say "MatchMaker Setup was completed successfully". and Click OK.

4. Occasionally you will encounter an extra window partway through the installation which says "A file being copied is not newer than the file on your current system. It is recommended that you keep your existing file." If you have not uninstalled the previous version of MatchMaker, you must answer "No to All". Otherwise it doesn't generally matter which way you answer and you can answer "Yes".

5. You should now be able to run the program the same way you run any other program from the Start menu. Watch for the red and white mushroom on a blue background. 

* If you have chosen not to install at this time, you need to go later to the folder C:\MatchMaker_Setup\ and double click on setup.exe (sometimes simply called setup). This is easiest to do using the program Windows Explorer, found under Accessories under All Programs on the Start menu, or the My Computer program (called Computer in some versions) on the Start Menu. One of these programs may already be on your desktop.
