@ algebrateacher CloneDVD does not use a "registration prompt" to register the program. The online key is what you are after. This is a small reg file, very easy of the slow internet connection
There are a few places where one can purchace the online key but the two most popular are :
Elby and Slysoft.
Dont worry you will only need need to download CloneDVD when there is a update. You will not regret buying.
