1. First, install Lightning Extreme Edition. It should be noted here that after the installation is completed, don't click "Experience Now", but click the close option in the upper right corner, otherwise the upgrade program will be automatically opened after Thunder opens.
2. Click the right mouse button on the desktop Thunder Extreme Edition icon and click "Open File Location";
3. Find the "XLLiveUD.exe" file in the pop-up folder and delete it;
4. Then create a new notepad file and change the name of the notepad file to the file name "xlliveud.exe" deleted in the previous step;
5. Then select the folder with the path "C: \ Program files (x86) \ Thundernetwork \ Thunderdata" and create a new folder named "Thunderpush";
6. Right-click the folder of Thunder Push newly created in the previous step, click Properties, and then click Security and Edit in the properties window.
7. Then click "Administrator" to change the full control right to "Reject", click "OK", and finally select "Yes" in the pop-up window. In this way, after we open the Thunder Extreme Edition, it will not be upgraded automatically.
