I need to add an activation code to an application when it is opened for the first time by a client.
Many moons ago i used a Keygen program.
On opening the VBA app it created a code that i fed into the keygen program, a keygen code was then created and this was given to the client to activate my application.
I would be great full if somebody has an idea to protect my application.
Any suggestions or examples that i should look at?
