Issue
The AdobeARM.log file contains similar entries:
[YYYY-MM-DD HH:MM:SS] IsTimeElapsed...
[YYYY-MM-DD HH:MM:SS] Minutes elapsed: MMM
[YYYY-MM-DD HH:MM:SS] Time elapsed is less than time limit - returning 0
Cause
By default, the Updater performs an update check every 3 days. The Updater adds the update check interval (3 days) to the value of tLasT_Acrobat. If the current date/time is less than this value, the Updater will exit without checking for updates and log the message.
Solution
Removing the tLastT_Acrobat entry will allow the Updater to perform the check.
Run the following via a Command Prompt.
REG DELETE "HKEY_USERS\.DEFAULT\Software\Adobe\Adobe ARM\1.0\ARM" /V "tLastT_Acrobat" /F
