When logging in as an user on a client, Terminal Server or Citrix you can get the following popup warning from Adobe Updater:

Insufficient Rights
Adobe Updater can be run only by users with administrator rights.

This problems comes when you're users don't have approciate rights to edit registry keys under their user registry hive. I've imported the following keys, with the logonscript (REG IMPORT blahblah.reg) or other ways to import registry keys while they logon (i.e. GPO, ScriptLogic, etc.), to solve the problem.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
@=”"
“AdobeUpdater”=-

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
@=”"
“AdobeUpdater”=”\”C:\\Program Files\\Common Files\\Adobe\\Updater5\\AdobeUpdater.exe\”"

This will clear the popup.
