Here are the instructions for uninstalling a program on a windows computer that was installed using the Windows Installer.

The first step is to find out the names of installed programs on the windows computer.  To do this enter the following command:

wmic product get name

You will then see a list of all the installed programs on the computer.  Find the name of the program you wish to install and enter the following command:

wmic product where name="The Name Of The Program You Wish To Uninstall" call uninstall

Wait a few minutes and execute the following command again to see if the program has been removed from the list:

wmic product get name

If the program has been successfully uninstalled it will no longer be displayed
