Security Manager 5.6
When upgrading Security Manager, getting an error about not being able to load SMCustomActions.dll
Install Windows Installer version 3.0 or later (version 3.1 is the latest at this time). The installer will then be able to check for the existence of .NET Framework 2.0 and install it for you.
There is a dependency of the Security Manager 5.6 installation upon Windows Installer 3.0. If this is not installed, the install will not be able to complete.
