I've got legal copies of LDD 2011 and C3D. I upgraded my computer to a 64 byte computer. When I loaded LDD it told me my authenication code was invalid. I called AutoCad they told me "Sorry, we no longer support ol Versions". I bought Carlson 2021, downloaded it, installed it and everything worked fine.
Then I loaded it on ly laptop, a 32 bit computer. Carlson wouldn't work.Called Carlson support they said "Sorry Carlson 2021 only works on 64 bit computers.".
Unless you're doing alot of engineering work a cheap CAD program will work just fine.
