Issues installing Sketchbook pro/ autodesk software

I was wondering if anyone has had issues installing any Autodesk software on their Mac? I have checked all the Autodesk support but nothing seems to work (updating downloads, downloading via firefox, even contacted tech support) I am still getting “no mountable file system” error. I haven’t gotten a response from Autodesk or their forums so figured I would try to ask here. Thanks a lot in advance

This is a disk issue with your Mac most likely.
