Are you talking about the CD installers? Nowadays, you're much better off using the fan-repacked version of the freeware release of the game.

Command & Conquer 1, Red Alert 1 and Tiberian Sun are all freeware, and have all been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. You can find them here:

Command & Conquer 1:

• Complete No-CD game installation pack (v1.06c r3, no videos, all music included) (also contains bonus missions originally exclusive to the Playstation and Nintendo 64 versions of the game)
• English videos pack (French and German video packs are also available on the website)

Red Alert 1:

• Web installer/patcher + some extras like the expansion pack videos from the Playstation version

Tiberian Sun:

• Full game (scroll down to "full game" and select "Full game (Windows)" in the dropdown)
