Adobe recommends that you use the Adobe Reader 8.0 uninstaller in the Add/Remove Programs utility in Windows to remove Adobe Reader 8.0. Occasionally, however, damaged files or a partial installation prevents the Adobe Reader 8.0 uninstaller from working correctly. Or, they could cause the uninstaller to leave files or empty application folders on the system after the removal is performed. You could also notice Adobe Reader 8.0 missing from the Add/Remove Programs list. Or, you could find that the installer only displays the Repair and Remove options when you try to install Adobe Reader 8.0.
Manually removing Adobe Reader 8.0 ensures that all files and folders are removed. These instructions are for removing Adobe Reader 8.0. If you have other/previous versions of Adobe applications installed, then be sure to remove only the files below that relate to Adobe Reader 8.0. These steps also remove any extra content (for example, Goodies or Functional Content) that installed with Adobe Reader 8.0. If you reinstall Adobe Reader 8.0, reinstall its extra content as well.
Note: It's possible that your system doesn't contain all of the files and folders listed in this document. If you do not find a listed file or folder on your system, proceed to the next file or folder on the list.
Some of these procedures require you to locate hidden files and hidden folders. Some procedures require you to locate files by their full filenames, which include extensions (for example, example_filename.ini). By default, Windows Explorer doesn't show hidden files, hidden folders, or filename extensions that it recognizes.
To show hidden files, hidden folders, and all filename extensions in Windows Explorer:
