Hu,
I have used Windows uninstall of all the Autodesk pproducts on this machine.
I have gone to Programs86 (etc)->Autodesk and deleted
Same with c:\Autodesk
and same with the two users in the App Data (Windows 7 machine) both local and roaming
deleted all mentions of AutoDesk from the registry
I once again after many times download from:
http://www.autodesk.com.au/products/autocad-mechanical/free-trial#
I have a key. I go through normall installation and then it comes up with a Red Circle next to AutoCad Mechanical 2015. You move the mouse over this circle and it says the product is already installed. It says if I want to install language packs etc click here and opens a folder. But there is no Autocad Mechanical installed and so all fails.
Any ideas?
Thanks
