This problem occured when trying to run the program and yes 3.5 and sp1 were correctly installed, but nevermind added a new partition today of x32 vista and all is working correctly on that so must just be some x64 issue, thanks anyway

i get the message "Viper Bot Loader has stopped working" everytime i try to run it. Im trying to run the FFXI version and the pc is running x64 Vista.
Please Assist
