If you have Reason 8.2 then you will have to either side-install 8.1 ( as 8.2 and 8.1 may be able to co-exist) or downgrade to 8.1 in order to use ReBirth. One important thing to note is that this procedure will not work with Reason version 8.2 or higher because Propellerheads have abandoned the 32-bit version of Reason. Next time I reinstall my computer I'll probably have to go through this all over again so I've made some notes which hopefully will also be of assistance to others. I was eventually able to get them working together on my computer (which runs Windows 7) but it took a few hours and its not easy, as the required information is all over the internet, not in one place. Probably because I'd been listening to some Acid Techno earlier in the week, I woke up this morning with the urge to play with a 303. So the obvious thing to do was to dig out ReBirth RB-338 and run it through Reason.
