The Xceed Component Installer will copy all the necessary files into the library's installation folder (usually in \Program Files\Xceed Components\Bin\ActiveX) and register the XCEEDZIP.DLL ActiveX / COM component. The only thing left to do is to make the control available to your VB 4.0 projects. To do this, perform the following steps:
Start Access 97.
Select the ActiveX Controls… option from the Tools menu
The "Xceed Zip Compression Library v6.x" entry should appear in the Available Controls list of the ActiveX Controls dialog.
Click the Close button.
Try reinstalling the Xceed Zip Compression Library from its setup program. Continue only if that didn't help.
In the ActiveX Controls dialog, click the Register... button.
Find and select the XCEEDZIP.DLL file (use the one in the Windows System folder that was copied there by the setup program) then click on the Open button.
The Xceed Zip control should now be available the "Available Controls" 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.
