I am about to install Windows 7 Professional and I have both the 32 bit and 64 bit versions available.
I remember reading a comment online that suggested that IronCAD ran better on Windows 7 32-bit version than on the 64-bit one.
Is that true?
Is the 32-bit or 64-bit version better for IronCAD?
Also - how about XP 64?
Will XP even be supported by IronCAD 12?
Obviously you need a computer that will run a 64-bit OS if you want to install one and I think any 32-bit version of Windows will only support up to 4GB of RAM at the most. I used Win XP Pro 32-bit until I ran into poor performance and needed more memory for larger assemblies. Now there's a lot of info out there comparing performance of the different versions but I don't think you need to look very far. I would just install Win7 Pro 64-bit since that is about the latest and greatest.
Here's a couple links that might help.
