It seems a permission issue on destination folder. Make sure you have sufficient privilege on below locations.
WIN: C:\Program Files (x86)\Common Files\Adobe\AAMUpdaterInventory
MAC: Library>application support>Adobe>AAMUpdaterInventory
If error persist, please send the RemoteUpdateManager.log via private message from location below.
- In Windows, the log file is in the %temp% location.
- In Mac OS, the log file is in the folder ~/Library/Logs/.
Thanks,
