How to install the RAWS32 from BE 2012 on an W2000 SP4 Server

Ok, i now that it is an old Operating System , but the Customer needs this Server at the Moment . 

When i try to install the Remote Agent on the Server and i try to start the Setup.exe the i become the error : it is not an valid Win32 application. 

Gives it an Trick to install the BE2012 Remote Agent on an W2000 SP4 Server ?
