Looks like you're missing an install file. If you have IT folks, ask them for help because they are probably the ones who deleted it.
If not, contact your reseller (company who sold you the software). They should be able to help you get the file you need.
A third option, you *might* be able to download the software from Autodesk and reinstall, as long as you have all the activation credentials.
