Android Question Missing jar file for library: package.xml

[Maxx1]

I'm trying to use B4A (Windows 10), but errors are occurring when trying to use the application.
1- Missing jar file for library: package.xml
2- The SDK Manager in the Tools menu does not open.
I have already removed and reinstalled the app.
I've looked for solutions on the forum, but to no avail.
Thanks

Everything is wrong with your configuration.

Carefully follow the installation instructions: https://www.b4x.com/b4a.html
And don't set the additional libraries to any existing folder.
