Standalone installation (no internet)

[KLL535]

Help me. How can I install this package on the Arduino IDE without internet access? What should I download? What should I write instead of .json? Or what folder should I put the downloaded .zip in?

Hi @KLL535
Converted as a discussion as it is not an issue with the core, please avoid to open issue for such question.
All packages are referenced in the json file:
https://github.com/stm32duino/BoardManagerFiles/blob/main/package_stmicroelectronics_index.json

With previous Arduino IDE 1.8.x, the json file can be local, file://
Nerver try with the Arduino IDE 2.x, you can try to use this way.
Download all packages and json file, update the json file to point to all the packages locally then give the json file to arduino using the file://

Thanks for the reply. But it doesn't work that way. The json file contains the URL link. And there are a lot of them. The Board manager tries to connect through them and returns an error. Is there really no way to download the local archive? And one more question, which version should I choose? For compatibility with Arduino IDE 1.8.3?

As said you have to change the url to file:// in the json file to pint on the local version...
1.8.3 is very old Arduino IDE, can't tell which version exactly is compatible.

The latest versions of the IDE just don't work. Because someone decided to drop support for Windows 7. It's easier to stop using Arduino IDE and use Cube IDE.
