Cannot Activate AutoCAD 2009

Recently my clients asked me to install Autocad 2009 into her notebook. The installation process ran fine at first. Then, came the activation process. I saw the product activation’s box below just after I double clicked the Autocad 2009 icon on Windows desktop



I clicked button Next and the weird looking interface appears. See below.

 

Operating System –-> Windows 7

Application Software –-> AutoCAD 2009
 
Solution:

1. Cancel the activation process first by clicking the button Cancel on the AutoCAD 2009 Product Activation’s box.
   
   
   


2. Now, press --> type regedit –-> click OK –-> click Yes to launch Windows registry editor. 
   
   
   


3. Double click HKEY_CURRENT_USER –-> Software –-> Microsoft –-> Windows –> CurrentVersion –-> Internet Settings –-> Zones
   


4. Then, you will see a subfolder just under the folder Zones indicated by the blue arrow below –-> right click on the subfolder –-> click Delete.
   
   
   


5. Click to highlight the folder 0 –-> find out data item named Flags –-> make sure its value is 0x00000021 (33)
   
   
   


6. Try to activate the AutoCAD 2009 again.
