This is a easy and safe installer to help people to downgrade. A voice explain the requeriments and the steps to downgrade, and the automatic setup install the necesay files to downgrade!
Light version doesn't contain the DOWNDATER folder, so it's totally legal to download and spread it.
This Downgrader is good for newcomers as it is more friendly and totally talks you along the processes, this can be used as an alternative to the other downgrader released.
