Photomatix Pro 64 bit v 32 bit- are there any hidden problems?

[Dagwood]

Could some kind person(s) enlighten me as to the issues I need to be aware of? I'm using Windows7 64bit and trying out various HDR trial downloads. One of these is Photomatix Pro 64bit but I see there is a 32bit version. As much of my software is 32bit should I stick with that or is there any advantage in using/purchasing the 64bit version?
Cheers Dagwood

I have just upgraded to 64 bit windows 7 .The photomatix I have is 32 bit and works absolutely fine .Including when merging several large raw files .

Matt, thankyou for that reply,I'll go ahead with the 32 bit purchase now. Can I ask whether or not you looked at other software first or was Photomatix Pro a straightforward choice for you?

I don't think there's any difference between what the 32bit/64bit versions produce, and I'm pretty sure that HDR Soft are very reasonable about what you're using. Buy a Photomatix licence, and you can have the Mac version, 32 bit Windows and 64 bit Windows version. Just use one of them at a time.
