I've seen a lot of posts in the discussion groups lately asking "How do I get my AutoCAD LT to run on Windows 7?" The short answer: AutoCAD LT 2010 is the only version of AutoCAD LT currently supported on Windows 7. There are a few known limitations, but most of them aren't mission-critical. For anything before that, you can try using the XP Compatibility mode, but there are no guarantees, and Autodesk can't help you if you have a problem. And for your reference, here's how the operating system support breaks down for the last few releases: LT VersionWindows 7 (1)Windows Vista (2)Windows XP2010XXX2009 XX2008 XX2007 X (3)X2006 X 1) Supported versions of Windows 7 are: Enterprise, Ultimate, Professional, Home Premium2) Supported versions of Windows Vista are: Enterprise, Business, Ultimate, Home Premium3) Service Pack 2 requiredGo to the original post...
