Steam's doing it's whole Steam Summer Sale thing, and both Clickteam Fusion 2.5 and it's exporters are on sale. I might try to go for it later on in the sale, but my copy of Clickteam Fusion 2.5 was gotten on a disc from Clickteam's store, not from Steam.
If I try and get a Steam version of an exporter, does it only work on a Steam copy? Is there a way to transfer my CD copy to Steam if I can't use it outside of Steam?
