I have tried to install Autodesk Revit MEP 2014 from Autodesk Design Building Suite premium. My PC configuration is
Windows 7 64Bit,12GB RAM, Intel Xeon Processor, Nvidia Quador FX 2000 Graphics card.
when I tried to install its shows error "Autodesk Revit 2014 is already installed". I tried to install from Deployment as well as from Media source but the error is same. I checked with "Unlicense tool" which is provide by Autodesk but its not shows anythhing in this. I have cleaned up registry also but still its shows same error. I need your people help to solve this problem.
