Sorry if anyone mistakes this for a new update, this is just a repost and minor update of the technical support FAQ from the forum (which I actually had to find via the wayback machine). Our forum and site is down, and unlikely to ever come back soo this is here to help anyone who has problems running the mod.
MEC2 won't launch for me!
Is C&C3 fully patched up? You'll need that in order to play the mod.
Is MEC2 installed to the proper directory? (it should be located so that the file mec2.big's filepath is mydocuments\cnc3\mods\mec2\mec2.big)
Does the mod show up in the C&C3 launcher? (pop your disk tray out and back in, it'll bring up a menu...hit the "mods" tab and see if MEC2 is listed there)
It's still not working!
The MEC2 shortcut needs to be set up so that it is something like this (right click the desktop icon to see the settings);
Target: "C:\Program Files\Electronic Arts\Command & Conquer 3\CNC3.exe" -modConfig "C:\Users\Bryan\Documents\Command & Conquer 3 Tiberium Wars\mods\MEC2\MEC2_1.0.skudef"
Yes that all needs to be on the same line (ignore the 'Target:' though)
Depending on your computer the exact location will be different, but the importance is that C&C3 points to CNC3.exe as well as MEC2_1.0.skudef, if you have to use a search to find the location of them on your PC.
If you still have problems, it is likely that MEC2 is in the wrong location. See the first post for where in the mydocuments area it should be. In that CNC3 folder should be; mods, screenshots, replays as well.
What if I have the Steam version of C&C3?
The problem with Steam is usually just the filepath for mods. It is 100% possible to get mods working with the Steam version of C&C3.
What if I have the Origin version of C&C3?
You're screwed. I've heard of someone getting it working (via replacing launcher exe's I believe) but by default the Origin version of most C&C's don't run mods well.
Ingame units are invisible and have weird polygons stretching across the screen!
Changing your video settings (in the options menu) so shaders is set to medium or above should fix this. If you still have problems set your model lod to low.
The game crashes when I try to change my settings in the options menu!
Load up normal C&C3 and change the settings there, they'll carry over to MEC2.
When I load up a skirmish game it crashes (or gives me an automatic win)!
This is likely caused by setting the AI to random, set it to a specific faction and you should be alright. (I do think this bug was fixed though)
If you have suggestions for other FAQ items to add here please post below. Also if you have any extra info on how you got MEC2 running on a Steam or Origin version of C&C3 please post.
