I have a machine that I tried to install IDSP 2014 on. It errored out during installation. When I tried to reinstall the Autodesk install wizard says C3D is already installed. There are no desktop icons for c3d and it is not listed under Programs or in the Program folder in the c drive, but all the other stuff that comes with it is there such as 'Civil 3 D as AutoCad 2014'. It is not listed in the control panel in W7. I tried to use the Autodesk uninstall tools but it isn't listed there. Still, the IDSP install wizard says it is and won't let me install it. What should I do? I don't want to reinstall Windows just to install c3d 2014.
