GDevelop Windows: 32 or 64 bit?

Not sure if anyone can answer this at all but…
So I developed my stuff under Ubuntu 14.04 64bit, but now I want to export my game as a windows executable, using wine. But I have no way to know whether my GDevelop runs and exports a 32 or 64bit executable. What is the current Windows version for? 32 or 64bit? Does the GDevelop installer detect this automatically, therefore does the wine version you install it with matter? Will executables be exported for windows be 32 or 64bit? Does that matter at all? I’m asking cause one of my windows testers reported a strange crash for which I can’t really pinpoint the cause for. The error log mentions that open32.dll. Is this relevant?
