You should only run the update if your current version is the same as the Update From version or above. You can determine what version you are currently using by going to Help > About on the program menu. You should not attempt to update earlier versions with these patch files – previous versions need more extensive upgrades. Customers with earlier versions should have received full upgrade CDs as part of their support contract. If you are a licensed customer and have not received the upgrade, please use our Contact Form to let us know.
Each download file is a patch installation program. Simply choose the Run option after clicking the download link.
