Make sure AdobeARM.exe process is not running (you can use Task Manager, select “Show All Processes” button) Collect and save somewhere all existing AdobeARM*.log files from User\Temp (C:\Users\[CurrentUserName]\AppData\Local\Temp) and C:\Windows\Temp folders. Enable MSI verbose logging - https://support.microsoft.com/en-us/kb/223300 Enable Adobe Updater verbose logging – set iLogLevel Reg_dword type value to 1 in the registry HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Adobe\Adobe ARM\1.0\ARM (64bit OS) Make sure no Adobe Acrobat or Adobe Reader is in use at the moment, as well as any Browser, Outlook, etc - Updater is waiting for files to be free before starting update installation. Go to C:\Program Files (x86)\Common Files\Adobe\ARM\1.0 folder and run AdobeARM.exe process. Wait a few minutes. Hard to say how long exactly, it depends on what Updater is already processing or waiting for. After you get error notification balloon, dismiss Updater (or after you no longer see AdobeARM.exe in the Task manager\Processes) and collect : all logs mentioned in step 2, latest MSIxxxx.logs from User\Temp and Windows\Temp folders (they may not exist, collect what is available) Please zip all collected logs and send zip file to me. Do not post in the forum! Note that the only personal info in the logs will be current User Name.
