Installation of CafeMan should not be a complicated task to be affraid of. Simply follow the steps;

Installing Server:
Run the Setup.EXE from the installation media and follow the setup instruction that appears on the screen, you are done.

Installing Client:
Run the Setup.EXE for the client from the installation media & follow the instructions appear on the screen.

WARNING: Don't run the client application unless you are prepared with the server.

During installations (mostly in Windows XP), your system may warn you that a file being copied is older than the file you already have, in such cases chose 'Keep'. Again, the installer may warn you that a DLL failed to register on the system, this happens when the specific file is being used by Windows itself, simply chose 'Ignore'. Your common sense won't betray you.
