I have the same problem, but my pc is a HP with Windows 7 Home Premium 64 bit, 4 gb en Ram 750 Gigas DD, and intel dual core 2.4 Ghz.
The steps are:
Put DVD and automatic detection.
But when I click a Install Autocad 2011
show in screen this error "Cannot install on the current operating system?"
Why show this problem if I have the requirements?
AutoCAD 2011 has 3 DVD’s:
Disk one is 32-bit Disk 1 of 2.
Disk two is 64-bit Disk 1 of 2.
Disk three is 32-bit and 64-bit disk 2 of 2.
Make sure you are inserting the 64-bit DVD for 64-bit operating systems or the 32-bit DVD for 32-bit operating systems.
