I have installed an Autodesk 2011 software without following the instructions and specifying a license server. Now, Autodesk is locked at product activation window, what should be done?
1- Open the registry editor by typing regedit in (Run) window, (Start Menu - Run), and browse to AdLM key: HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R18.1\ACAD-9001:409\AdLM .
2- Change the Type Dword value to 1.
3- Copy licpath.lic file from Autocad software download page to "C:\Program Files\Autodesk\AutoCAD 2011" (default) installation directory and restart your PC.
Note: If the software is not AutoCAD, but some other Autodesk component like 3DS MAX, go to AdLM key in relevant location in registry editor and copy licpath.lic file to relevant disk location accordingly. (For example: HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\3dsMaxDesign\13.0\MAX-1:409\ADLM Type Dword value will be set to 1 and licpath.lic file will be copied to "D:\Program Files\Autodesk\3dsMaxD" non-default location.)
