Not able to download SAP NetWeaver AS ABAP 7.03 SP04 64-bit Trial

Hello,

I am not able to download SAP NetWeaver AS ABAP 7.03 SP04 64-bit Trial , it gives me an error -not able to read the source file.

Please let me know , I just need a system access with a developer key so that I can practice my coding part in ABAP.

My system is windows 7 (home edition) + 4 GB RAM + 64 bit , is it compatible ?

Thanks

Bharat
