Check my compatibility list in my signature.

no offense,as nice had that spreadsheet is (nice enough that I downloaded it), it does not help me in this situation. Also I'm guessing that U stands for untested and the Y means Yes. is that correct?

Do you mean you don't have the compatibility mode option because you haven't registered the dll or that you do have compatibility mode but the installer isn't registering it?

I can confirm that compatibility mode did work on the installer for this game.

IIRC the 97/98 C&C CD doesn't require compatibility mode. (Check the file dates on the CD). This is the ver that EA released free a couple of years back.

I don't have the game in front of me right now but easiest way to install if you have the old ver is to install on a modern OS or in a VM and copy over the files.

You can also try this: (I've never used it)

It may also be possible to extract the files. If it's installshield then a installshield extractor should work.

Mechwarrior 2
Use DOSBox for the DOS version.
IIRC, the game does work in NTVDM but you may need NOLFB.

If you must play the Windows ver then MW2Hook should work and if you have the Titanium ver you'll also need DGVoodoo. (old ver of DGvoodoo not the new ver 🙁 )

Yes, U untested, N Not working, Y, working, P Problem, Purple is emulator or port.

Didn't the Win2k compatibility tab only show for shortcuts and not for the EXEs themselves?

I thought so too.
I have compatibly mode on and the games still say I'm using Windows NT. I tried both 95 and 98 compatibly mode.
My copy's of c&c are the Westwood copy's and the dates on the disk are 95/96

Maybe try an older version of ACT?

I would think a newer versions would be better. If I recall I never had problems installing mw2 in Windows xp

I suggested an older version since newer ones might not even install on Win2k and you are trying to make it run with the APIs of such an old version of Windows. You do not have to deal with the API changes of Win10.
