Error "Need to reboot the computer" after you run the Adobe Update Manager

After you run the Adobe Update Manager, you receive the error message, "Need to reboot the computer." You keep receiving the error message each time you restart.

Solution 1: Remove the AUM transaction file.

Remove the AUtrans.xml file from the Documents and Settings\[user name] \Application Data\Adobe\Updater folder.

Solution 2: Remove the Adobe Updater.exe key from the registry if it exists.

Important: The registry contains system-related information that is critical to your computer and applications. Before modifying the registry, be sure to make a backup copy of it. Adobe does not provide support for problems that arise from improperly modifying the registry. Adobe strongly advises you not to modify the registry unless you have experience editing system files. For information on the Windows Registry Editor, see your Windows user guide or contact Microsoft Technical Support.

1. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run.

2. Select the AdobeUpdater.exe key (if it exists), and then choose Edit > Delete.

3. Click Yes in the Confirm Key Delete dialog box.

Solution 3: Search for and delete the AdobeUpdater.rbt file if it exists.

Adobe Updater on Mac OS X does not find available updates

Sometimes the Adobe Updater application does not report available updates for Mac OS X. You can encounter this problem when you use the Adobe Update Manager to check for updates for currently installed Adobe applications. This problem can occur whether you choose  Help > Check For Updates from within an Adobe application or use the Adobe Updater application in the Utilities folder.


Set the correct 775 (recursive) permissions for the Adobe folder under /Library/Application Support. Enter the following in the command line in Terminal:

sudo chmod -R 775 /library/"application support"/adobe


Adobe Updater does not find updates (Creative Suite 2 applications)

When you choose Help > Updates from an Adobe Creative Suite 2 application, the released updates for that application are not available.

The specific update you are trying to download is not listed when you select Show Details in the Adobe Updater dialog.

When you choose Help > Updates, the updater sometimes displays this error message: "There are no updates available at this time. Please note that update for the following products cannot be determined at this time. Adobe Updater."

Solution 1: Download the updates manually.

If you are accessing the Internet from behind an authenticating proxy server, download updates manually from the Adobe website.

To determine if you can access the Internet from behind the authenticating proxy server, contact your network administrator.

Note: Sometimes Adobe updates are not immediately available on Adobe.com. If the update you want is not available, then try again at a later time.

Solution 2: Add crl.adobe.com to your proxy server exception list.

If you are accessing the Internet from behind a non-authenticating proxy server, add crl.adobe.com to the exception list of your proxy server. Also make sure that port 80 is open. For more information about your proxy server exception list and ports, contact your network administrator.

Solution 3: Delete the Data folder and run the updater again.

If you are accessing the Internet from behind a non-authenticating proxy server, delete the Data folder from the Adobe/Updater folder and choose Help > Updates again.

You can find the Data folder here:

  • Mac OS: Users/[username]/Library/Application Support/Adobe/Updater folder
  • Windows: Document and Settings/[username]/Application Data/Adobe/Updater

Cannot disable the auto-check feature of Adobe Update Manager

You have followed the directions in Disable automatic check for updates | CS3. Even so, starting one or more Adobe CS3 applications still activates the Adobe Update Manager.


Rename the folder that contains the Adobe Update Manager application.

  1. Browse to the folder that contains the Adobe Update Manager application.
    • On Mac OS: /Applications/Utilities/Adobe Utilities/Adobe Updater 5
    • On Windows: C:\Program Files\Common Files\Adobe\Updater5.
  2. Rename the folder. For example, rename it "Updater5disabled".
