You say what you say, I think the WinBuilder should have a 64-bit version. Best regards
Sure, that is a wish, and like any wish, it *needs* not in itself a proper justification
The point was simply that this particular wish (perfectly respectable like any personal opinion or wish) has NO valid, objective reason backing it.
On the other hand, while I presume that making a "sheer" x64 version of the builder (with the proper compiler or whatever) would most probably be relatively easy for Peter, there are IMHO a number of drawbacks as it will likely create a nightmare of compatible vs. incompatible .scripts.
As I see it the actual advantage of Winbuilder is not (with all due respect to all the work that Nuno and Peter put into it) in the builder itself, but rather in the projects and .scripts that were created (which ALREADY anyway suffer from cross incompatibilities) and introducing a 64 bit version of it is likely to aggravate the problems.
But, please correct me if I am wrong, there is no issue whatever in using a 32 bit builder to produce a x64 build, so the ONLY difference would be some (possibly) SLOWER building times, while being capable of accessing more memory (that won't be used).
Do read the given link, the memory limitation in 32 bit is only "by design" and can be worked around rather easily.
