How can I delete old versions of an Action Wizard from current version of Action Wizard

Hi,

I have users who have old versions of an action wizard (version 1.10 and version 1.11) I created.  I now have an update which is version 2.0.  I want to make it so that when they import version 2.0, the code looks for version 1.10 and 1.11 and deletes them.

I realize there is a way to manually do this by going to Edit Actions and deleting the old action wizards.  However, I don't think my users will actually do it such that there will be 3 versions on their system.  I can imagine they will use the other versions which have some bugs.

Hopefully someone can help.  I am using Adobe Acrobat XI.

Thx.

Sue
