Ways to install Ford IDS and Mazda IDS in a computer/laptop:
One native install (e.g. Mazda IDS) and the other one on VMWare
Install and boot multiple operating systems using something like Boot It Bare Metal from Terabyte. Btw, I can recommend this one as it works like a charm. Never had any problems managing my partitions.
Have both in vmware -
you can find them on here as premade images just browse to automotive software forum then to vmware
using vmware is very easy and it has the advantage that if you mess up the program installation then you can just reload the image and be up and running in a few minuites
also with vmware you can stop it going onto the internet by disabling the VM network adapter, but still be on the internet with your computer so you can google the problem or find the file you need and then just drag and drop it inot the VM
IMPORTANT: the best way is to use VMware.
Some install both Ford and Mazda on real machine by install Mazda first, after that change the path of Mazda, then install Ford. But not successful by this method!
