Hi there, I've been trying to install Autodesk Inventor since last week but I'm unable to do so. I downloaded Inventor Professional 2015 from Autodesk website through an educational licence and selected the Browser download method. the whole package downloaded successfully and when I ran the extractor, It gave me the following message, "product consists of multiple files. at least one file is missing or has not been downloded yet". so I downloaded inventor again and again the same problem. I also downloaded the Inventor Prof 2014 but again the same problem. I also tried changing the extraction path but that too didn't work. I'm using windows defender just for info. a screen shot is also attached. Please help me with this issue. thank you
