priyadoshi08,
I assume from your post that used the Control Panel "Programs and Features" unistaller and then may have also manually deleted the C: Program files and Program X86 Autodesk folders. I have uninstalled AutoCad 2007 using only the Programs and Features uninstaller without further problems, but newer versions may be more "protective". I once (12.12) restored my HD from a system image and had to reactivate all the Autodesk products as though they were installed on a new computer, whereas Solidworks and Adobe CS4 did not require it.
The following three posts/articles seem to address the problem of a computer having residual traces of AutoCad such that it presents a block to reinstallation.

These seem to be progressively more thorough but I can not say whether these work. If you do try the third remedy which visits the dangerous realm of regedit, for safety (Oh, how I suffered in
that dark and lonely land during the bleak days of Windows 95!), carefully backup your system's Registry before doing any editing!
Beyond these measures- if nothing works- you might consider a full reinstall of OS and applications, which might, in any event give you a cleaner, faster running machine.
As I have not had this problem personally, I hope others will comment on the above.
Best of luck!
Cheers,
