Hi, I already installed the b4a but I cannot run it even as a button with hello world. This the error I've got:

Please help. Thank you.

It looks like B4A is misconfigured. You are probably using an old core library. Uninstall B4A, make sure that all files in the installation folder (Program Files (x86)\Anywhere Software\Basic4android) are deleted and reinstall B4A.

Thank you, Sir. I already run it correctly. My mistake was I included and copy pasted my old library files in the library folder of the b4a. Thank you, again.
