I honestly don't know if thats a trust worthy site to get it from or if the files are infected or corrupted. there doesnt seem to be any official utorrent version archive. Perhaps someone else can verify the credability of the oldapps.com site.
After i found out how bloated and fake it had become after i tried the first version of 3. I copyed the 1.6 program installation folder from a diff machine i had it on and just pasted it over to mine, (after fully uninstalling v3 first ofcourse) and it works fine, even on clean format OS it doesnt require install. Only other way i can think of to get old versions is torrenting them LoL.
Also just fyi if u didn't already know... If the speed your refering to is accurate and not a newb confusion between Mbits and MBytes per sec.. you will probably be targeted from whoever trying to crash your torrent, unless its unpopular/non copy writed material your torrenting. of course may differ depending what country your in. Assuming you own the connection and theres not an admin or NAT shuttin you down.
