Can't reinstall Adobe CS4 Production Premium on Mac with OS10.6.8

[Domcheung]

I am using a PowerMac Pro with os10.6.8. I installed Adobe CS4 & CS5 production premium in this computer. Both products were purchased years ago with discs (box version). Few weeks ago, something wrong with the adobe CS5. I then try to uninstall the CS5 but the alias uninstaller can't run, as it prompted that no original application can be found. There are Adobe CS5 folders left in m computer which may cause the CS4 version can't be installed. The indtallation stuck/stop when it finish around 30% and show installing the Adobe AIR.  

Please help to advise how can I reinstall and activate the CS4 as well as the CS5 with the original discs.

Also how can I delete the left Adobe folder from my computer?

I have tried this and other like "MacCS5CleanupUtility" but still don't work. 

Want to know how to manually delete the Adobe folders left in the Applications folder in my computer?
