LONG TIME SKETCHUP USER HERE, RECENTLY UPDATED TO V 2026 MIGRATED OVER ALL MY EXTENSIONS JUST FINE EXCEPT HOUSEBUILDER. iT OPENS BUT THE TOOL BAR IS JUST A B UNCH OF GREEN BOOXS WITH X'S IN THEM. TRIED UNINSTALLING, DOWNLOADED A FRESH COPY, WONT INSTALL THROUGH EXTENSION MANAGER. REALLY FRUSTRATED AT THIS POINT, I'VE BEENT RYIONG FOR AN HOUR AND I USE THIS TOOL ALMOST DAILY ANY HELP WOULD BE MUCH APPRECIAT4ED. AS I AM CONSTANTLY ON THE VERGE OF HAVING AN ANURISM OVER THE CONCSTANT ISSUE IN SKETCHUP LIKE THIS. THANX, UNHAPPY CUSTOMER SINCE 2017
