Hi everyone, How can I know, or what can I do, to make my applications runs with one version or another one of .NET? I mean, I have write an application, but the destination desktop PC, only has .NET version 1.1, and can't install any other version. As I have developed it, it uses .NET version 2.0. But how can I rewrite it, to be usable with this version 1.1?. The application only uses Bitwise, CryptoDesktop and RegistryDesktop libraries. Thanks in advance, Jesus.
