Yes, can you send me your serial number in private message?
I am unable to unable to activate my AutoCAD Civil3D 2012 64bit student licence - error 400 appears.
Could anyone help me with the activation? Thank you in advance.
Error 400s are typically associated with an invalid request code and can be resolved with a manual activation code.
Please send me your serial number through private message (click on my arlinpega.bibat profile name and then “Send this user a private message”) together with your request code.
In order to generate an activation code we will need the request code that is displayed on your monitor after you begin the activation procedure. Following are the steps to retrieve the request code:
1. Run the program
2. Pull down menu 'Help'
3. Click on 'About'
4. Click the Production Information button at the right hand corner
5. Click on the Activate button
6. On this page you will be able to view Product, Serial Number and Request Code
For future reference, you can contact our Registration and Activation directly.
