I download the installer and run without problem.i did triple before i wrote...maybe the File is corrupt ?
B4J was installed properlyI think this is similar to Android don’t allow install non play store apps.
Try searching you problem on google
Its set to "from anywhere"Which version is the windows on your new notebook?
Check Settings ->Apps & features to see if it is set to The Microsoft Store only.
