Step # 1. Java Development Kit (JDK)
A prerequisite of the B4J upgrade installation requires having either the OpenJDK (& OpenJFX) 11.0 runtime or the Standard Oracle JDK 8 already installed on your computer.
If you do not already have the Java JDK installed, please refer back to how to find a Java Development Kit (JDK)
Step # 2. Download and Start the B4J (Basic4Java) Installer
The standard B4J installer takes care of handling new installations as well as upgrades from previous versions of B4J.
A direct link to the B4J installer can be found on the B4X website: https://www.b4x.com/b4j.html#installation. The following is a screen-shot of where to find the link on the B4J installation page:
If the installer link is not working, please refer to the homepage of Anywhere Software at https://www.b4x.com/ and look for new links to the B4J product and/or installation page.
After downloading the
B4J.exe installer to your Downloads folder, double-click the
*.exe installer file (or initiate running within your browser download list). At this point a warning message may appear, depending on your Windows User Account Control settings.
Step # 3. The B4J (Basic4Java) Upgrade Wizard Screens
The following wizard screens (pages) are presented in order that they appear.
Wizard page 1.
Wizard page 2.
Wizard page 3.
Wizard page 4.
Wizard page 5.
Wizard page 6.
Step # 4. Open B4J and confirm path to the Java JDK
Open the B4J IDE from your existing link in the Windows Start menu or Taskbar.
After opening the B4J IDE, click on the "Tools" pull-down menu and select "Configure Paths" to open the "Paths Configuration" dialog to confirm your previously installed and configured path to the
javac.exe is still set.
Then click "OK" to save any path changes, or "Cancel" to close the dialog.
