The only games I've found from '05 that have a problem with Win7 are due to the copy protection.
Starforce is perhaps the worst, followed by Tages and SecureRom. In most cases it is a problem with 64bit OS's (XP too).
In some cases the game will install and give an error message to the effect that it cannot finish, but the game is in fact installed, but the DRM is not.
Games that use Tages can sometimes be fixed with their 64bit update -
TAGES, the AAA Copy Protection System.
Some games can be installed onto a 32bit machine and copied to the 64bit machine and will run (not sure in this case).
Other games will run with a noCD patch. There is a noCD fix at Mega Games (PC fixes left column of home page). The A51 fix more complex than most as it has several files which I assume (don't have the game) all go in the main install folder with the A51.exe.
I usually move the original .exe (and other files) into a new folder for backup before
moving the new ones into the games install folder.
Then - as has been suggested by MH, some just are not doable, or may require a Virtual Machine -

In my collection (100+) there have only been two - Beyond Good and Evil (not the re-release) and Splinter Cell Chaos Theory that I have not found a fix/workaround for (I haven't tried a VM).
If there is a fan site for Area 51 there may be fixes available from the community.
I found a 64bit installer for the old classic Grim Fandango on one such site.
