The Xceed Component Installer will copy all the necessary files into the library's installation folder (usually in \Program Files\Xceed Components\Xceed Encryption Library [version]) and register the XCEEDCRY.DLL ActiveX / COM component in the BIN subfolder. The only thing left to do is to make the control available to your VB 5.0 projects. To do this, perform the following steps:
Start Visual Basic 5.0.
Create a new project or open an existing one.
Select Components… from the Project menu.
An entry named "Xceed Encryption Library v1.1" entry should appear in the components list.
In the Components dialog, make sure the "Xceed Encryption Library v1.1" entry is checked in the components list. This will make it available for use in your applications.
Click the OK button. The Xceed Encryption control icon should now appear in the components toolbox.
Try reinstalling the Xceed Encryption Library from its installation program. Continue only if that didn't help.
Click the Browse… button.
Find and select the XCEEDCRY.DLL file (use the one in the Windows System folder that was copied there by the installation program) then click on the OK button.
The "Xceed Encryption Library v1.1" entry should now appear in the components list.
The License method must be called to license the library for runtime use. This applies to both registered users as well as users of a time-limited free trial license.
