Re: Command and Conquer Remastered -- Failed to launch
I had same issue but managed to get C&C Remastered to launch by selecting it in the EA App, clicking MANAGE, then View Properties and then adding -REDALERT to the Advanced launch options. After clicking OK to the admin prompt, the launcher successfully ran and allowed me to select my C&C original game or Red Alert.
Hopefully this will work for others too until EA sort out the bugs in this awful EA app.
