Hi all, I'd been playing around with this issue a couple of weeks ago as per below thread:
https://answers.ea.com/t5/Command-Conquer-Games/Command-and-Conquer-Remastered-Failed-to-launch/td-p/12253286
Just thought I'd share my findings here. There is an error in the CnCRemastered\__Installer\installerdata.xml file. The EA app uses that file when calling the launcher (ClientLauncherG.exe).
The XML allows parameters to be passed when calling the exe but parameters need to be preceded by a valid switch symbol in the XML eg - or -- or /
The XML has the parameter DUMP_FULL but because the switch is missing before it, it fails to launch and errors out.
If you specify your own parameter in the app (via View Properties) it seems to override the invalid XML parameter and it launches the game.
Whether you use my suggested parameter from the other thread (-REDALERT), the parameter suggested in this thread (-NOSPLASHPRELOAD) or just some made up switch (like -ILIEKTURTLEZ) it doesn't matter, the game will still launch. Alternatively, you can also correct the XML if preferred and you're comfortable with doing that.
It's doubtful if even valid parameters actually take effect, since the exe just launches the launcher.
By the way, you have to use a switch symbol (whether in the EA App or in the XML, as it is how the EA app parses them).
