If the software files are in a folder and zipped then unzip them first , then put them in the (vehicle folder), not in the vehicleCP. there you will find USA Asia,Europe.etc. make sure you put them in the correct location and unzipped. all files must be inside the folder, not out. if such folder does not exist then create them, make sure the first letter of each brand/make is in upper case, the rest lower case. example if it looks like this
honda, it is wrong. it has to look like this Honda. the H in upper case, some of you press the cap lock and some just the shift key, either way is fine. when all this vehicles make folders are made just extract everything inside this folders. is pretty much copy and paste, nothing to install.
make sure to use the same version software on vehicles that shares them. like Honda/Acura, Nissan/Infinity etc. good luck.
