HI, > The new ant-script-based install like 4.13.0 works fine but the legacy > installs will have trouble with AIR 15.
How is 4.2.1 a legacy install as it's still using the "new" ant for air code. Can you provide more information to what the error is and if possible what is required to fix it. ie is it a config file change or an installer change? Thanks, Justin
