Installing Oracle Forms and Reports on a 64bit machine
This couldn't have been easier

Forms and Reports here (Fusion Middleware) and alternative (non-Fusion) here. You may need an app server - not sure.

This was a relatively easy Google - that normally merits a -1, but since it's your first post here, I'll let it slide. Do they not have similar rules about question research on StackOverflow (where you have a rep. of nearly 1.5k)?
