Lite-On Hw 1635S

Hi,
I’ve just bought my son a nw PC with an Lite-On HW 1635S drive. Several CD-ROMs won’t install properly. This applies to several veyy new games and - for example SonicStage 3.1 programme. These installed easily on my older PC.
The message I get is that the application is not a valid Win32 application.
I’m a newcomer to computers so I really don’t understand what’s going on.
Any help would be appreciated .
