Enterprise Toolkit Windows Registry Reference

Updater-Win (Windows Updates)

These preferences control how the Updater works for the Acrobat family of products 9.2 and 8.1.7 and later. Earlier product versions used the Adobe Update Manager (AUM); for those versions, see AVGeneral.

For an Updater Quick Key, refer to the Quick Key Library.


This preference category contains the following subfeature(s):

Updater (other settings)

These preferences control when the Updater is invoked, how and when a check for updates should be made, and other behaviors. Note that while the Updater is often disabled in enterprise settings, it's also possible to leave it enabled and configure whether updates happen automatically or silently. For DC products, the web component updater can be configured independently of the product updater. For an Updater Quick Key, refer to the Quick Key Library.

HKLM Path 64 bit: HKLM\SOFTWARE\Wow6432Node\Adobe\Adobe ARM\1.0\ARM
Summary Sets the time that can elapse without a successful update before the Watchdog dialog appears suggesting the user manually update.
Details This is an internal key that is not visible unless the admin creates it manually. When the Updater successfully obtains a manifest it records the download date. iInterval specifies the time interval that is allowed to pass from that download date to a a successful update. The default is 135 days. If the time has elapsed, a dialog appears suggesting the user might want to manually get an update from adobe.com. Possible values include:
  • 135 days
  • User specified.

Data type integer: DWORD value > REG_DWORD

Version # 9.2-10.1
HKLM Path 64 bit: HKLM\SOFTWARE\Wow6432Node\Adobe\Adobe ARM\1.0\ARM
Summary Records the last year the Updater checked for updates; iLastD records the day.
Details By default, the Updater performs an update check every 3 days and records the year and day of that check if 1) no updates are found in the Manifest for the user's current product configuration or 2) if updates have been found and successfully installed. Prior to 10.1, the date is recorded in iLastY and iLastD. For 10.1 and later, the date is recorded in tlastT_Reader or tlastT_Acrobat. If 3 days have not passed, the Updater exits. If more than 3 days have elapsed, the Updater looks for updates.

The last and most current value may be written to HKLM or HKCU. Because the Updater doesn't need elevated privileges to initiate a check or download updates, it will write to HKCU. However, on systems where elevated privileges are required, it writes to HKLM. Therefore, when checking and troubleshooting the last check date always verify the values in both locations.

This value is not customizable as the value is written at runtime.

Updater Logging

The log file is a file generated and appended to at runtime with status, operational, and error information describing what the Updater is doing. This information helps diagnose runtime problems and should be included with any support requests. Logging behaves as follows:

  • Logging cannot be disabled.
  • Log file size is not limited during an update.
  • Log files are appended to each time the Updater runs, there is a 1MB limit on old logs.
  • Log files are only backed up once; therefore, there should never be more than two logs on the system.

Summary table
iLogLevel Sets the log level to either brief (0) or verbose (1).

Data type integer: DWORD value > REG_DWORD
Default 0
Version # 9.2+
HKLM Path 64 bit: HKLM\SOFTWARE\Wow6432Node\Adobe\Adobe ARM\1.0\ARM
Summary Sets the log level to either brief (0) or verbose (1).
Details Log file size is not limited during an update. However, since log files are appended to each time the Updater runs, there is a 1MB limit on old logs. Size limit behavior is as follows: If an existing log size is bigger than 1 MB, the Updater truncates the log. Old log files are backed up once as AdobeARM-backup.

Logs reside at:
  • Vista-Windows 7 (64 bit systems) %USERPROFILE%\AppData\Local\Temp\AdobeARM.log
  • XP (32bit systems) %USERPROFILE%\Local Settings\Temp\AdobeARM.log
Set the log level as follows:
  • 0: Brief
  • 1: Verbose
