Overview

Adobe recommends that you use the Adobe Acrobat 8 uninstaller in the Add/Remove Programs utility in Windows to remove Adobe Acrobat 8 from the computer. Occasionally, however, damaged files or a partial installation can prevent the Adobe Acrobat 8 uninstaller from working correctly. They can also cause the uninstaller to leave files or empty application folders on the system after the removal is performed. Sometimes, Adobe Acrobat 8 is missing from the Add/Remove Programs list. Or, you find that the installer only displays the Repair and Remove options when you try to install Adobe Acrobat 8.

Manually removing Adobe Acrobat 8 ensures that all files and folders are removed. These instructions are for removing Adobe Acrobat 8. If you have other/previous versions of Adobe applications installed, then be sure to remove only the files below that relate to Adobe Acrobat 8. These steps also remove any extra content (for example, Goodies or Functional Content) that you have installed with Adobe Acrobat 8. If you reinstall Adobe Acrobat 8, reinstall its extra content as well.

Note: It's likely that yours 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, you proceed to the next file or folder on the list.

Before you begin

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:

  1. In Windows Explorer, choose Tools > Folder Options.
  2. Click the View tab in the Folder Options dialog box.
  3. In Advanced Settings, select Show Hidden Files And Folders.
  4. Deselect Hide Extensions For Known File Types.
  5. Click OK.

Remove Adobe Acrobat 8 using the uninstaller

The uninstaller is designed to remove everything installed by Adobe Acrobat 8. When you start Adobe Acrobat 8 for the first time, or when you modify the preferences, Acrobat sometimes creates new folders. To ensure the complete removal of all folder and files, proceed to "Remove remaining folders and files for Adobe Acrobat 8" below after using the uninstaller.

Use the uninstaller:

  1. Choose Start > Control Panel.
  2. Double click Add/Remove Programs.
  3. Do one of the following:
    • If you installed Adobe Acrobat 8 from the Adobe Acrobat 8 CD/DVD, then select Adobe Acrobat 8 and click Remove. Follow the onscreen instructions to remove Adobe Acrobat 8.
    • If you installed Adobe Acrobat 8 from the Creative Suite CD/DVDs, then select Creative Suite and click Remove. Follow the onscreen instructions to remove the Adobe Acrobat 8 component.

Note: When you run the uninstaller, you are prompted to remove, keep, or transfer activation. If you plan to reinstall Adobe Acrobat 8 on the same machine, consider keeping your activation. However, after you complete the manual removal, it's likely that you'll have to reactivate Adobe Acrobat 8. If you plan to install Adobe Acrobat 8 on a different machine, transfer your activation.
