@Ngoc.nguyenTR4N3 ,
The Installation & Licensing forum may provided better suggestions.
Make sure to follow the Installation Instructions:
AutoCAD 2022 must already be installed.
1. Select and download one of the language packs below.
2. Double-click on the downloaded EXE file and click Install to extract the AutoCAD language pack files.
3. The language pack installer will start after the extraction is completed.
4. After accepting the license agreement, click the “Install” button to install the downloaded AutoCAD language pack.
5. After installation, you can launch AutoCAD in the selected language by double-clicking on the desktop shortcut created for each language, or from the Windows Start menu.
Please select the "Accept as Solution" button if my post solves your issue or answers your question.
