Installer Changes

The SDK and Open Server installers have been enhanced for version and backward compatibility.

The SDK and Open Server installers now check that the version you are installing is compatible with, and can be installed on top of the version in your destination directory.
When the bug fixes in the version in your destination directory are unavailable in the version you are installing, the installation is considered as incompatible.

If the already installed version is compatible, installation proceeds normally.
If the already installed version is incompatible with the version you are installing, the installation process stops. You can:
- Override the error to continue, or,
- Abort the installation. Check the software download site to see if a compatible version is available.
For backward compatibility, the installer installs all security and directory driver file versions from 15.7 GA to 15.7 SP100.
