Removing Preferences, Licenses and Receipts
There are various further steps that need to be taken if you don’t plan on reinstalling Microsoft Office: Mac 2011 in future.
The following steps will require you to use the Finder to access various folders on your hard disk drive. For instance to remove the Office Preferences, open Go > Home > Library > Preferences and find all files beginning com.microsoft. Drag these to Trash along with the Microsoft folder.
You should also remove the helper files (com.microsoft.office.licensing.helper.plist and com.microsoft.office.licensing.helper), found in:
Finder > Go > Computer > [Your hard drive] > Library > LaunchDaemons
Finder > Go > Computer > [Your hard drive] > Library > PrivilegedHelperTools
Meanwhile licenses can be removed by opening Finder > Go > Computer > [Your hard drive] > Library > Preferences > com.microsoft.office.licensing.plist.
You will also need to discard the Application Support data. Open Finder > Go > Computer > [Your hard drive] > Library > Application Support and drag the Microsoft folder to Trash.
These steps can be completed on Max OS X 10.5 (Leopard) and 10.6 (Snow Leopard) by removing the Receipts, found in Finder > Go > Computer > [Your hard drive] > Library > Receipts. Identify the receipts files as those beginning Office2011_, and move these to Trash.
If you use Snow Leopard, proceed by checking for files in other locations: go to Finder > Go > Go to Folder > /private/var/db/receipts, click Go and discard all receipts beginning com.microsoft.office.
