Kerberos for windows 4.1 on windows 2008 SP2

[Anish Kurian]

Hello,
I am trying to install MIT Kerberos for windows 4.1 on windows 2008 (R1)
SP2. I am getting an error saying the packaging is not compatible with the
windows installer.
Windows 2008 R1 uses windows installer 4.5 and unfortunately i cant upgrade
my OS to R2 which uses installer 5.0
Is it possible to upload kerberos 4.1 on your website , having packaged
with windows installer 4.5 ?

Thanks so much
