QLM protects your Excel VBA code with the same level of functionality and license protection that are supported with VB.NET. With QLM Excel License Protection, you can provide permanent, trial or subscription based licensing to your customers. Your customers can easily activate their license online when connected to the internet or offline if they are not connected to the internet.
Our extensive license protection API is fully supported on Excel VBA.
In order to prompt the user for a license key and activate it, you simply launch the QLM License Wizard from your Excel sheet. The QLM License Wizard eliminates the need to develop any complex code in your Excel VBA module to capture a license key and activate it. The QLM License Wizard is a standalone application that you launch from your Excel application. For more details about invoking the QLM License Wizard, refer to this article.
