I am unable to install Autocad to Windows 7 64 bit. if any body can can help please let me know

I had the same issue. If you get a message saying that you can't install it on your OS then you probably have the 32 bit version; just go get the 64 bit.There's actually an emulator installed on Windows but it doesn't work on this for some reason. The Program Files(x86) folder is where the 32 bit programs are.

Please tell me  How i can install

Which version of AutoCAD? AutoCAD 2010 is officially supported in Vista 7 (including the 64bit version). Make sure you are installing the 64bit version of AutoCAD included on your official installation media.

version of CAD 2010 and i want to install it on Windows 7
