Install.bat fails without error message

System

I recently setup a Windows 2003 server with SP1, then downloaded the installation files for TS6.5.0.0 (build 41240b). Upon running the executable the Teamsite subdirectory was created with the install.bat file included. When I try to run this it simply fails after a few seconds without any error message. I downloaded it twice in case of corruption, but got the same result.

Any ideas are much appreciated!
