It seems like I have mistakenly replaced the library with the one with an old version. But I don't know where to find the library of the latest version to replace it again.
I have already installed with the full procedure once. That works fine. Now that I have only uninstalled and install again and this error pops up.
And a little wonder, after I have uninstalled, rebooted the computer and install again, the B4A didn't ask me to locate the license txt or reenter the registered email. Does it indicate something wrong?
All that I can say is that this artifact is part of the recommended items. It should be installed with B4A Sdk Manager. You can also download the ready to run SDK. https://www.b4x.com/search?query=ready+sdk
