SAP NetWeaver 7.01 SR1 on windows 7 ?

hi all ! I want to know if this is even possible. Im trying to do it but Im getting this error at step 2.

Running msiexec failed with return code 1603: Fatal error during installation.

Commandline was msiexec.exe /norestart /L sapmmcX86u.log /i sapmmcX86u.msi /qn

I know this OS is not supported, but all my previous programs seems to work just fine... Any help is appreciated.
