Q: Where does PGP keep its license file within OS X? I was using a trial from PGP. Now have a license supplied by the company I work for.
Upon trying to overwrite/upgrade - PGP is reporting that its using the 'old', namely trial license. Which has long expired.
How can I completely rid my machine of PGP - and thus be able to install a fresh copy?
Where does this pesky license file reside?
OS: 10.6.2 
PGP: 10

A: I am not sure where the license file is stored, but to answer your second question, PGP has installed files in several locations around my system. (OS X 10.5.8, PGP 9.x)
First, back up your PGP keychains, and any virtual disks you may have.  Then I would delete the following files.
/Applications/PGP
/Library/Application Support/PGP 
/Library/Frameworks/PGP.framework
/Library/Frameworks/PGP.Client.framework
/Library/Frameworks/PGPui.framework
/Library/Frameworks/PGPwde.framework
/Library/Receipts/PGP Desktop.pkg
~/Library/Preferences/com.pgp.desktop.plist
~/Library/Preferences/com.pgp.engine.plist
~/Library/Preferences/com.pgp.pgp.plist

Once you have deleted those files, you should be able to run the installer for your new version of PGP, enter your license info, and you should be good to go.

A: If your PGP keys are backedup, you can use AppZapper to uninstall PGP, then reinstall it fresh and import your company-provided license. The AppZapper trial lets you uninstall 5 apps before registration and it does a great job of removing EVERYTHING an app has added to your system. 
It will optionally let you deselect some files for removal in case there is some data from the app you want to keep around. You can even use it as a way to discover all of the paths the various files live in (the list TheWellington provided looks pretty complete to my eyes, but you never know).

A: I suggest you contact the PGP vendor and ask them for help ... or read their FAQ (provided it exists).
