IncrediMail is a third-party e-mail reading application designed for Windows-based computers. Instead of reading your mail via your Web browser, you can have IncrediMail download all of your e-mail right to its main program window. This allows you to view and read e-mail messages even if your computer isn't connected to the Web. Performing a "Repair" of IncrediMail involves installing a fresh copy over a copy that has become corrupted or is otherwise giving you issues.
Click "Control Panel."
Click "Programs and Features."
Click "Repair." A new window will open. Click "Next" to perform a repair of your computer's installation of IncrediMail.
