The One-Click License Update facility allows your customers to directly
update the key by double-clicking the .upw or .nlf file. On Windows 98, double-clicking
a .upw or .nlf file initiates the Secure Update Utility rather than

need to tune your application installer for creating certain registry entries
(specific to .nlf and .upw files) at the client machine. These registry entries
are listed in the following table:
For .nlf Files
