Sometimes I blame my English language, but when I read again and again, I found it very descriptive, when I said "one of the major problems spreading the internet nowadays -and for long back- can be solved of introducing 64 bit DLLs" ... how did you get to relate that with internet so you came up with your reply "64bit has nothing to do with the internet" ???
if you just do a little google search, for "Adobe PDF Reader" and "Visual Studio" you will see what is meant by the sentence and what is meant b 64-bit DLLs in modern technologies, and then you will figure out all stuff ..
Cheers
