Windows Installer folder - Microsoft Community
answers.microsoft.com › en-us › windowsClick the start button, choose Run..., then type c:\windows\installer. At this point, an explorer window should appear that reveals the contents of the installer folder. BE CAREFUL :-) Now that you are in this folder, you will want to be very careful with what you do in there. The "delete" key is not your friend in most cases...and it is less so in a folder like c:\windows\installer.
