It is not possible to associate files any longer during installation (47877)

It is not possible to associate files any longer during installation and when I un-installed my previous version it disassociated SQL Navigator with the files that it was set to open with. How can I associate these again?

Due to the use of the new Quest Installer, the associate files option is not able to be included in the installation process.
