Hello friends! I have virtualized AutoCAD 2012 x86 using Spoon Virtual Application Studio 2012. I configured everything correctly. However, the tweaks on virtual app to get over this licence error didn't work. That means I'm missing something. What I want to ask is, why does this error pops up? My serial number is correct for sure, I even activated online but the thing is I get this error all the time. Probably a certain file is missing...But which file? If I can determine the exact registry key or file that app requires, I can easily solve the problem. Can you help me out about which file or reg key it is? Thank you.
