Working with no issues on Windows 7 x64:

Command & Conquer 95 - The First Decade version with 1.03 Rev.4 patch. Use "Set Affinity..." in Task Manager or ForceCore program to force the game to use only 1 CPU if you have a multicore system. Kill explorer.exe before launching the game to fix color corruption.
Command & Conquer: Red Alert - The First Decade version with 1.03 Rev.4 patch. Use "Set Affinity..." in Task Manager or ForceCore program to force the game to use only 1 CPU if you have a multicore system. Kill explorer.exe before launching the game to fix color corruption.
Command & Conquer: Tiberian Sun - The First Decade version with 1.03 Rev.4 patch.
Command & Conquer: Red Alert 2 - The First Decade version with 1.03 Rev.4 patch.
Command & Conquer: Red Alert 2: Yuri's Revenge - The First Decade version with 1.03 Rev.4 patch.
Command & Conquer: Renegade - The First Decade version with 1.03 Rev.4 patch.
Command & Conquer: Generals - The First Decade version with 1.03 Rev.4 patch. Takes long to launch for the first time (can even crash, just re-launch if it does), will launch ok afterwards.
Command & Conquer: Generals: Zero Hour - The First Decade version with 1.03 Rev.4 patch. Takes long to launch for the first time (can even crash, just re-launch if it does), will launch ok afterwards.
Command & Conquer 3: Tiberium Wars - Retail, patch 1.09.
Command & Conquer 3: Kane's Wrath - Retail, patch 1.02.

I did not include C&C: The Covert Operations, RA: Counterstrike, RA: The Aftermath, C&C: The Covert Operations and Tiberian Sun: Firestorm because they use same executables as their respective games. All of these addons run fine too.

With this and RA3 (which I didn't try yet, but the 1st post says it does work) we've got the whole C&C series running on Windows 7 x64.

Civilization 4 - Beyond the Sword (BTS) (x64)

Run all installs as "Administrator" - i.e. right-click "Run As"
Download all patches in advance do not do in-game updates.
Install Civ 4, patch Civ 4, Install Warlords, patch Warlords, Install BTS, Patch BTS
