i know nuts about computer stuff, so got a friend to come look. also cant solve the problem.
when i put in other softwares, eg games, downloaded freewares like "live stone views", i have no problem installing them.
but when i put in the disc from my 40d, my friends 50d, downloaded dpp 3.5.2 and 3.6 from canon site, all cant install. it doesnt auto-run, when i click the .exe file, it starts extracting, after that it ends there.
i have norton 360, so not virus.
pls advice, but pls use layman explaination can?
