We're about to upgrade our Acrobat users from X to XI. We've got a number of users who have created custom signature appearances they use when signing documents. In the past when we upgraded Acrobat these signature appearances were lost. Is there a way to move existing signature appearances to the new version when upgrading so that they don't need to be recreated by users?
Search the system for a file called "appearances.acrodata". It should be in the Acrobat user folder, in the Security subfolder. The specific location depends on the version of Acrobat/Reader and OS. For example, on Windows XP:
C:\Documents and Settings\user\Application Data\Adobe\Acrobat\11.0\Security\appearances.acrodata
