CoH: Modern Combat

So now that I have the new patch installed (1.015) how do I go about launching it? I briefly saw something that looked like "-mod ModernCombat" but I cant seem to find it again.

All info you need is on the "download" section of this website. The instalition is simple with the "relaunch" CoH version since the installer basiclly already sets-up the install directory.

Make sure to remove ALL Modern Combat files before going after 1.0015.

Yes you can find the instructions for a Desktop shortcut or Steam Shortcut here:

I am also having an issue. I have the steam relaunch version (v2.700) and have never downloaded the mod before. I downloaded version 1.15 and it installed fine in the company of heroes relaunch folder. My issue is when I run C:\Program Files\Steam\steamapps\common\Company of Heroes Relaunch\RelicCOH.exe it only runs the original COH game and not Modern Combat. I've check all my folders and cannot find a ModernCombat.exe file to run.

Add "-mod ModernCombat -dev" to the end of the "Target" in the Properties menu of the Shortcut. Do it like any other mod.
(If you're using Steam, go to your Library and right click the shortcut, Launch Options, and add what I said above to it)

I have tried to add MC to steam through the shortcut but it does not appear in the selection. I tried browsing for it and adding "-mod ModernCombat -dev" but I can't find it.

For Steam, you've got to make a shortcut of the mod manuall, then go to "Add non-Steam game" then "Browse" and find the shortcut you just made. Once you do that, right click the Steam shortcut, "Properties" then add "-mod ModernCombat -dev" to the end of the Target.

No need to make a shortcut.

Do this in your Steamlibrary: Find Company of Herose (New Steam Version) --> Rightclick on it --> Properties --> Set launch options --> -dev -mod ModernCombat

That's it. Want to play normal CoH again, delete everything in "set launch options".

It says that file can not be found when I add it to target.

Then you probably don't have either MC installed, or it's installed in the wrong spot. All I can say.
