Step 2: Go to Help→Install New Software…
Step 3: Select the “ASTRA Update Center” which you created during the initial installation.
Step 4: The category “ASTRA IDE” Should now appear in the main area – check the box next to this
Step 5: Uncheck “Contact all update sites during install to find required software” (unless this results in an error later).
Step 6: Click next twice
Step 7: Accept the license terms (ASTRA is available under a GPL3.0 license) and click Finish
