Please read the first issue, I didn't patch the game because it's not even available. I just created shortcuts, installed the launcher, and hooked the games. However, I did give it a shot and reinstalled Tiberium Wars, and nothing changed. It still shows unable to launch C&C 3.
Anyway, appreciate the response and here's the error log:
UPDATE:
I just read the log and fixed it myself, lol. Apparently I just needed to run the game as administrator and switch the game's network setting from the Hamachi IP to original IP. Thank you admin for reminding me about the log. I hope this thread helps other people who have similar issues.
