When you've downloaded MailBee.NET package installer MailBeeNetObjects.msi, the first thing to do is to close all applications which may use MailBee.NET. If Visual Studio .NET is running, please close it too. After that, you need to remove your existing MailBee.NET Objects installation. To remove existing version of the product, use Add / Remove Programs in Control Panel. Then, new version of MailBee.NET can easily be installed: just run the installer and follow the on-screen instructions.
Now, you have the new version of MailBee.NET Objects installed, but your applications powered by MailBee.NET Objects still reference to the old version. Thus, you should update references in the projects and rebuild the applications powered by MailBee.NET Objects.
For Visual Studio .NET projects, you should remove reference to MailBee.NET (open references of the project in Solution Explorer and remove reference to MailBee.NET), then add new one. Rebuild the project.
For non-Visual Studio .NET environment, you should manually replace MailBee.NET.dll file in the /bin subfolder of your application and rebuild the project. After installation of MailBee.NET package you can find MailBee.NET.dll file in installation folder (by default it is "C:\Program Files\MailBee.NET Objects" on 32-bit Windows or "C:\Program Files\MailBee.NET Objects (x86)" on 64-bit Windows).
