I installed Autocad 2013 in windows 7(64 bits) and i couldn't install because software is 32 bits. So kindly help how to install 32 bits software in 64 bits windows 7.
Exactly, it should install without problems on either 32bit or 64bit Windows 7. Did you try restarting your machine? Sometimes you may have some leftovers from programs that you may have closed that have left behind some errors in the running memory. Restarting the machine before a major install, eliminates this possibility. Also look carefully as all suggestions on the link phil22 provided. You have to be a little bit crazy to keep you from going insane.
This post and the link provided by phil22 are almost identical... same person with two log-ons perhaps?
