Every night a new build of my program is made and copied to a /Builds/ folder. I have a Windows machine that I want to have uninstall the program then install the latest version of the program from the /Builds/ folder.

Currently the build results in two separate setup.exe files which are InstallShield installation wizard executables. I want this to happen every night after the build finishes:

• Uninstall first component.
• Uninstall second component.
• Install newest build of first component using setup.exe.
• Install newest build of second component using setup.exe.

I figured that there probably already exists a software solution for automating installations like this. Are there any software solutions out there than can do what I need? Preferrably for free?
