>>>>>I am interested to hear from forum members how important (or not) you think it is to be able to offer 64 bit applications vs. 32 bit currently (regardless of language used). Do you feel that being able to offer 64 bit exes is important or not really an issue in the field of general business applications?

>>You ask for the importance of being able to deliver a 64 bit application. I would say that it's our job to make sure that people are told that the application is 64-bit compliant. That's all they really need to know.

>What about the fact that our 32bit apps need to run in WOW64 compatibility mode under 64bit O/S? Doesnt this have a performance impact? Or is it so minimal as to be a non-issue?

minimal if one can go by the measurements done when Vista/Win7 established 64Bit for normal users. Usually more than equalized by better RAM usage (disc cache)
