We have priced the component at a level where we hope that companies or individuals using multiple copies will respect the license agreement. Attachments are enabled in the registered version but not in eval copies. When you register make sure that the name you want displayed is included in your registration information. Normally this will be a company name. Changes will NOT be made once the product has been shipped to users who register.
Users can upgrade for free for minor version changes.
For example, upgrades from version 1.00 to 1.99 are free. The upgrade from 1.99 to 2.0 may carry an additional license fee. If a fee is associated with obtaining the upgrade it will be noted on that page. Uninstalling the old DLL is not necessary. If the DLL has been loaded you will get an error message saying the file is in use by another process.
