Ok, everyone who still get’s them Error Code 1601/1603 problems LISTEN HERE. but first I wan’t too know if this worked for you, if so please email me at webmaster@bored.mrcrash.net, thankyou.
Solution: I’ve tried ALL the problems on this forum, nothing worked. I found out that my problem was easy and simple too repair, if your running Norton anti virus double click the icon in your task bar, Click Options, Instant Messanger and where it says “What instant messangers to protect” unclick MSN Messanger (Recommended). click ok and get out of it, now try and install, it SHOULD work, it did for me.
Hope this help’s 🙂
