TechTool Pro 6.0.6 and Mac OS X Tiger

Updating TechTool Pro 6 for Mountain Lion required that we made changes to the TechTool Pro installer.  The result of these changes is that the TechTool Pro 6.0.6 installer no longer supports Mac OS X 10.4.x.  In order to maintain compatibility with these Macs, we have included the TechTool Pro 6.0.4 installer in the Extras folder on the current TechTool pro 6 DVD.  You can use this installer to install TechTool Pro 6, and then choose 'Check for Updates...' from the TechTool Pro 6 menu to update TechTool Pro to version 6.0.6.
