I have an application that have beeen running for the past year.

This morning I tried to modify a form (VB6 sp4) and I get a message saying that "licence informations are not found. You no longer have the proper licence to use this component" (translated from french message).

The component is mscomctl.ocx (tabstrip, toolbar, treeview, ect...). The file is still under system32 and is registered in the registry.

What can cause the licence to be invalid? Do i need to reinstall VB6 ?

Thanks.
