First off I am of the understanding that this question is like asking how long is a piece of string, but here goes. How would I go about researching how to change a 32 bit program into a 64 bit program. There is a Ispai Filter called Ionics Isapi Rewrite Engine. it is great but it is only compatible on 32 bit machines. The source is there, but how and where would I start to make this compatible with a 64 bit machine?
Thanks in advance,
