I have downloaded it.Can i just install it on the last version folder ?Sometime it automatically uninstal older one before install new one

 Maybe a simple and clear step by step guide for updating would be a good thing from DAZ

Each time i am facing to some problems when i upgrade: sometime the old saved files don't load , some time one plugin stop working, some duplicated files message,etc

Each time i see some users asking the same things for example about plugins  (upgrading or not, which need to update which don't need)
