RUNTIME.ICD Error ==> safedisc issue (and since the update came with OS it's taken for granted)
Game Does Not Recognise Disc ==> ditto
Introduction Video Crash ==> codec issue (again, once you have last service pack you are fine)
Windows Compatibility On CD2 ==> CD2 is always required (SafeDisc you know). Then there are only two things where compatibility could be set (ie executables)
One is clokspl.exe, which is Safedisc stuff, and doesn't even need administrator rights cause it's all done by the system SecDrv driver
The other is Runtime.exe.. which is only needed during installation.. to be copied on the hdd. Otherwise it's never invoked.
Set Single Core Affinity ==> the emblem of fixes "just because"
EDIT: after an additional Windows update, SafeDisc is a problem again.
I could have just mentioned the normal workaround to re-enable the service.. but for W10 users' sake I guess the fix now included in the page is better
EDIT2: there is supposedly a bug with videos and the original release though
