You may notice below that I recommend to "turn off Airport" during installation and to run "sudo dscacheutil -flushcache" after updating the /etc/hosts file. I'm not sure if these steps are necessary but I recommend to do so anyway. Also notice the link to Acrobat 9 Pro at the bottom of the post:

REMOVE OLD ADOBE INSTALLATIONS (IF APPLICABLE) BEFORE INSTALLING ADOBE CS5Remove the following Adobe applications, folders and files before installing the Adobe CS5 Master Collection (but check notes below this list first):/Applications/Adobe... (everything with Adobe)/Library/Application Support/Adobe/Library/Application Support/FLEXnet Publisher/Library/Preferences/com.adobe... (everything with com.adobe)/Library/Preferences/FLEXnet Publisher~/Library/Application Support/Adobe~/Library/Application Support/Adobe/Acrobat~/Library/Preferences/Acrobat~/Library/Preferences/Acrobat Distiller Prefs~/Library/Preferences/Adobe... (everything with Adobe)~/Library/Preferences/com.adobe... (everything with com.adobe)

A few notes:- / is the system root folder (which you can find in Finder by clicking on the hard drive icon at devices)- ~ is the User folder (which you can find in Finder by clicking on the home icon at places)- I strongly recommend to delete the "/Library/Application Support/FLEXnet Publisher" and "/Library/Preferences/FLEXnet Publisher" folders if you have old Adobe applications installed. Keeping an old version of this folder can cause a variety of licensing errors. It will automatically be regenerated with the CS5 installation.- Obviously, if you're attached to your old Adobe application preferences, don't delete the preferences files in the system and User libraries. There is no harm in doing so, they'll be automatically regenerated but by deleting them you will loose your user preferences. I prefer to start with a clean system but that may not be the case for everybody.

INSTALLATION OF ADOBE CS5Disconnect from network/internet (Turn AirPort Off). Double click "CS5_Master_Collection.dmg" to install the Adobe CS5 Master Collection. Whilst installing CS5, ensure that you choose "Install this product as a trial" and DO NOT enter any serials. If you've already installed CS5 applications using a serial, load any of the installed CS5 applications and select Help > Deactivate. Quit all of the installed CS5 applications.

TERMINALLaunch a Terminal window (in /Applications/Utilities) and copy and paste:sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts

Hit return and type your admin password.The "hosts" file should automatically open in TextEdit.

TEXTEDITIf the following lines are already part of the "hosts" file close it and continue with the "Finish" section. If not hit return (in the opened "hosts" file) and copy and paste following lines:127.0.0.1 activate.adobe.com127.0.0.1 practivate.adobe.com127.0.0.1 ereg.adobe.com127.0.0.1 activate.wip3.adobe.com127.0.0.1 wip3.adobe.com127.0.0.1 3dns-3.adobe.com127.0.0.1 3dns-2.adobe.com127.0.0.1 adobe-dns.adobe.com127.0.0.1 adobe-dns-2.adobe.com127.0.0.1 adobe-dns-3.adobe.com127.0.0.1 ereg.wip3.adobe.com127.0.0.1 activate-sea.adobe.com127.0.0.1 wwis-dubc1-vip60.adobe.com127.0.0.1 activate-sjc0.adobe.com
