This driver is copyrighted and is not shareware and not freeware.  In its current development state it's available for download for free but that won't be true indefinitely.

The driver has been installed and tested on Windows 2000 and Windows XP.

RWODBCForSAP-1.0.3.zip
This is the installer for RadioWorks ODBC Driver 1.0.3 for SAP. Extract the files to a temporary directory and run setup.exe.

The driver uses the Microsoft .NET environment.  You may need to install some of these other packages depending on the errors you get when you run the installer:

Microsoft .NET Framework Version 2.0 Redistributable Package (x86)
You need this package if you get a message, “The dynamic link library mscoree.dll could not be found.”

Microsoft Visual C++ 2005 Redistributable Package (x86)
You need this package if you get a message, “MSVCR80.DLL is missing.”

LIBRFC32.ZIP
You need the DLLs in this archive if you get a message, “The dynamic link library LIBRFC32.DLL could not be found.” If SAP is installed on your machine this shouldn't happen. These DLLs go directly into the Windows\System32 directory.
