Why now CIS 5 is not install on Windows Server 2003?
After reinstallation Windows Server 2003 installer of CIS 5 give error “not supported platform”.
Before CIS 5 successfully worked on given version Windows.

yes !!!
Why CIS is not installed on server 2003 ?
Yes it had some problems working on server
for example the firewall was blocking active directory and DHCP
but i could live with firewall turned off
i can not live without antivirus
I chose to use CIS because it was working on server 2003
please make CIS working on server 2003 again !!!
you could say “not supported platform - use at your own risk”
instead preventing usage completely.
allowing working some way (beta or some) on server 2003 You could gain experience on server
and make CIS better.
Please let CIS works on server 2003 again !!!

thanks
best regards

CIS has never been supported for Server platforms.

Please let CIS works on server 2003 again !!!
