Manually remove Adobe Help Center | Windows


Adobe recommends that you use the Adobe Help Center uninstaller in the Add Or Remove Programs utility in Windows to remove Adobe Help Center. Occasionally, however, damaged files or a partial installation can prevent the Adobe Help Center uninstaller from working correctly. Or, they can cause the uninstaller to leave files or empty application folders on the system after the removal is performed. Other issues include Adobe Help Center missing from the Add Or Remove Programs list or the installer only displaying the Repair and Remove options.

Manually removing Adobe Help Center ensures that all files and folders are removed. These instructions are for removing Adobe Help Center1.x and 2.x. If you have other Adobe applications installed, be sure to remove only the files below that relate to Adobe Help Center.

Note: It's likely 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.

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.

Determine the version of Adobe Help Center you are using

Before you begin removing Adobe Help Center, determine which version of Adobe Help Center you are using.

Determine which version of Adobe Help Center is installed, do the following:

  1. Navigate to Program Files\Adobe\Adobe Help Center.
  2. Right-click ahc.exe and select Properties.
  3. Choose the Version tab in the ahc.exe Properties dialog box.
  4. Note the File Version that is listed.

Remove Adobe Help Center using the uninstaller

The uninstaller is designed to remove everything installed by Adobe Help Center. When you start Adobe Help Center for the first time, or when you modify the preferences, Adobe Help Center sometimes creates folders and files. To ensure the complete removal of all additional folders and files, proceed to "Stop AhcRemind" below after you use the uninstaller.

Use the uninstaller:

  1. Choose Start > Settings > Control Panel > Add Or Remove Programs.
  2. Select Adobe Help Center 1.x or Adobe Help Center 2.x and click Remove. Follow the onscreen instructions to remove Adobe Help Center.

Note: It isn't always possible to remove Adobe Help Center using the uninstaller. If Adobe Help Center is not listed in Add Or Remove Programs, proceed to "Stop AhcRemind."

Stop AhcRemind

Stop AhcRemind:

  1. Open the Task Manager by pressing Ctrl+Alt+Delete.
  2. Click the Processes tab.
  3. Select AhcRemind.exe if available and choose End Process.
