why do so many softwares say to close all applications before installtion? I can understand about closing certain applications when installing certain softwares but what about installing huge sofwares that take ages to complete, like games?

I like to browse the web or listen to radio when installing games becuase they take so long. is there anything wrong with it?

why do so many softwares say to close all applications before installtion?

Can you juggle 9 rabbid badgers at the same time? Probably.

But should you...?
