You can't run both. both methods don't work on each version. The Steam version's shortcut directs the game to run through Steam, so the Retail verification doesn't run the same. That's why it's in the Steam client instead.
i'll tinker some more tomorrow. if there's any solution ideas throw them at me. copied all dlc list codes and put them in the new dlc list folder and everything looks good nothing comes up
I don't understand the part that I have marked in bold.
@CurtArchitect Did you manage to silence other cars? Actually the COG55 sounds almost perfect, but I can not give that silence inside the other cars. And it's true, people on the street talk very loudly. Another problem with COG55 is that you can not modify the handling. I've tried it everywhere and nothing works for me. He needs more direction in the curbs; upload it to 50 instead of 40 as a default is what I want but it does not work changing the handling in the mpapartment DLC which is where the handling and vehicles.meta files of this car are located. To finish the car itself must be changed in patchday10ng because if you do not keep appearing the misco car by default of the game. I changed it for a Bentley but I would like to change the steering and a little suspension to make it a bit more smooth.
