Here are the details for installing the current BETA release of the IDE:

First, if you're NOT using Windows 11, you might need to install the WebView2 Runtime from Microsoft. Some products, like Office 365 now pre-install WebView2 for you, so you might not need this step. Here is a link for the official WebView2 runtime:

DOWNLOAD LINK FOR THE LATEST RELEASE:
https://github.com/WaynePhillipsEA/twinbasic/releases

Extract the twinBASIC_IDE_BETA_xx ZIP file somewhere, and then run the twinBASIC.exe from the root folder to launch the IDE.

Some of the current known issues:

• if the WebView2 runtime is not available, the twinBASIC executable does nothing, and currently does not report an error
• closing the IDE with dirty editors will NOT warn you, and you WILL lose any unsaved changes
• currently the IDE window opens in maximized mode and can't be un-maximized
• moving of panels is currently disabled
• resizing of panels is currently disabled
• DEBUG CONSOLE and WATCH expressions are not always working when reading variables from the active debugging callstack
• IDE doesn't yet allow entering your tB licence key
• the three code editor drop-down lists are not yet populated
• rename refactoring is currently broken
• CONDITIONAL breakpoints not yet supported (normal breakpoints are)
• the OUTLINE panel doesn't have any icons
• no TEST EXPLORER yet
