Few applications are actually designed specifically for Vista x64. It does run just as well as on Vista x86, though, without special tweaking.
Does AbiWord run in Vista 64-bit Edition? I have Home Premium and I'm hoping that it can run. I can't find information anywhere about this, positive or negative. I'm not looking for people saying that they have done it or something, I want to know if it's designed for it. You can run anything on anything with a bit of work. I'm interested only in whether it's meant for Vista 64-bit.
