ADWORKS COMMERCIAL TROUBLESHOOTING v4.2.0 PREMIUM TOOL DOES NOT OPEN - Extract the ZIP completely; do not run files from inside the ZIP preview. - Keep START_HERE.html and every ADWORKS tool folder together. - Try current Chrome or Edge on Windows. PWA / INSTALL BUTTON DOES NOT APPEAR - Confirm the suite is being opened from HTTPS hosting, not file://. - Reload once while online. - On Android Chrome, also check Menu > Install app / Add to Home Screen. - On iPhone/iPad Safari, use Share > Add to Home Screen. - Some browsers decide when to show an install prompt; the manual Add to Home Screen route is still valid. OFFLINE MODE DOES NOT WORK - First open the HTTPS-hosted START_HERE.html while online and allow the initial PWA load to finish. - Reload once, then test in Airplane Mode. - If an older version is stuck, remove the installed shortcut/app, clear only that site's cached data if needed, and install again. - Version 1.3 pre-caches all primary suite modules instead of waiting for every tool to be opened individually. SAVED DATA IS MISSING - Use the same device, browser, browser profile, and site origin. - Avoid Private/Incognito mode. - Clearing browser/site data can erase local records. - Restore the latest JSON backup from Contractor Business Hub. IPHONE/IPAD - Use Safari for Add to Home Screen. - Avoid in-app Messenger/WhatsApp browsers for installation. CALCULATIONS Treat all outputs as preliminary. Verify actual site conditions, electrical code, structural requirements, equipment specifications, permits, protection, compatibility, and prices before final implementation.
