Environment

ITMS 8.x

Cause

Known issue.

This has been addressed by disabling the auto-launch of package creation wizard in the case when SIM is installed on an incompatible OS version.

This is not a product installation but a package creation wizard.

Resolution

You could try the following (if you know for sure the OS version mentioned is supported):

1. To allow installation following DWORD registry entry can be created:

HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\EnableInstallOnUnsupportedOS = 1 

However, for obvious reasons, it is recommended not to be used without understanding the possible risks of an unsupported OS version (in order to avoid future unexpected behavior).
