At our company, we have a set of applications some developed in .NET, some in C++ and some in Delphi. Not ideal, but that's what you get when you have legacy applications. We started off with Quick License Manager to protect our .NET apps. We then discovered that you can also use Quick License Manager with Delphi via a COM interface. It works pretty nicely. The same for our unmanaged C++ apps which use the COM interface. All ours apps are now protected using Quick License Manager. We're pretty happy to have one product protect all ours apps.

QLM has been stable and reliable. This is what we like about it: it's a complete hands free solution from the moment a customer purchases our software. We just sit back and watch the sales happen.
