So they didn't include a 16bit Windows on Windows (WOW) emulation layer, only 32bit WOW. It's just that Microsoft decided to draw the line in how far back they will support older applications, But, it says that although AutoCAD R14 and AutoCAD 2000 are 32bit applications, they wont install onĦ4bit Windows because the installer program for those 2 are in 16bit and 16bit isn't supported on Windows 7 64, but it is supported on Windows 7 32bit.īy the way Andre, it's not a CPU limitation, because you can install a 32bit version of Windows 7 on a 64bit machine no problem, and that gives you 16bit support.

Longbow mention it on their website - their tools get all 32bit versions of AutoCAD >= 2008 working on 64bit, and all versions <= 2007 working too. This can be beneficial to other community members reading the thread.
