Another installer is currently running

[ingeneizel]

When trying to install Adobe after effects on my new macbook pro, I am getting the following message. "Another installer is currently running, which must be closed before installing this product.  Please close other installers."  I do not have anything else running.  I have shut down my system and upon starting up again, immediately try the install.  I get the same message.  Any suggestions?

Launch the Task manager to "Show processes from all users" and make sure there's no other installer running as user type "System". Check for the "Windows installer" service and end the task. Also, confirm if any third-party app or Windows update is not installing updates.
