I'm trying to update Flash to version 12 on OS X 10.6.8. After I have downloaded and started the installer, I'm asked to agree with the license. Doing this enables the install button, but clicking it does absolutely nothing.
I have no idea how to continue with the installation at this point. My system log gives the following clue:
|2014-01-25 03.40.30||Flash Player Install Manager||Unable to execute privileged task.|
I'm not asked for a password for the installation, nothing happens when I click the install button.
I was finally able to install after I rebooted the machine, I have no idea what caused this, but it resolved itself so I'm happy.
