This method is much more convenient than the licensing method that uses FlexNET. To use Keignan, please do the following:
1) Be sure to make sure that your Internet connection is completely disconnected. Make sure your device is not online. Then install the software.
2) Run the software after installation. Initially, you will be asked to activate the request. Click enter a serial number.
3) In the next window, click Activate. Now add the serial number to one of the following terms (note that you do not have to copy the serials written below! Serials are entered manually in the software and do not copy):
666-69696969
667-98989898
400-45454545
066-66666666
4) To enter the Product Key, please open the AUTODESK.2019.Product.Keys.txt text file and get the product key for your product.
For example, the Product Key for AutoCAD Arctic Trend 2019 is: 185K1
5) Click Next. On the Activation Options page, you will be given a phrase called Request Code. Select this value and copy it with the combination key Ctrl + C. Now, you need to run the ****** file. If your operating system is 64-bit, xf-adsk2019_x64_ (2018mod) .exe file and if it is 32-bit, run xf-adsk2019_x86_ (2018mod) .exe file as Run as Administrator.
6) Click on the ρá†ch option to display the Successfully Patched message. Now, place the amount you copied in step five in the Request box and click Generate. Copy the amount generated in the Activation box (make sure that you copy and do not copy).
7) Go back to the software environment and activate it. Click on the option I have an activation code from Autodesk. Sixteen boxes appear for you. Right-click on box 1 and hit Paste to copy the amount obtained from step six.
8) Click Next. The whole thing is working and your software is fully activated.
Tip 1: If step 5 does not appear on your Activation Options page, it's because you are not online. To fix the problem, start the activation process again from the start (close the activation page and the software and run it again) until this page appears for you.
