Obviously, Elana hasn't run into the " bug, or spyware, adware,etc." involved in running so-called "freeware", but she'll learn soon enough.
As to your Microsoft question, why do people always want programs for free....Now, most software programs can be loaded into(for most) up to three separate computers for HOME use.....
secondly, anytime you download a program, that requires "license" verification, you should always perform that upon the first prompting for the "key". You can try, un-installing the program, then re-installing the program again, this time using the patience needed to finish the entire process...
Have a great day, always investigate thoroughly, any freeware products before "trying" them.........some adware, spyware, and even viruses can be downloaded along with these FREEWARE programs.....
