My problem is that it is unable to install AutoCAD Civil 3D. There was a working C3D 2010, 2011 (Hungarian) on my mashine (win 7 64-bit), and i tried to install C3D 2012, but it didn't manage. There was a problem with .net I think, because the log files showed that. I tried a lot of things that I found on discussion groups and on other forums, but it didn't help. The biggest problem is, that I can not use the C3D 2010, and 2011. At first I couldn't use them, then I couldn't uninstall them. Then I used the Revo Uninstaller (I read about this software on one of these disc. groups), but then I couldn't reinstall any version of the software. So please help, because I am unable to work, and I would not like to reinstall the whole operation system. Now there isn't any working version on my computer.
I attached some of the log files and error messages.
Thank you in advance
