Had updated Win XP to Win 7 in January which worked fine. Later Opera stable 20 run perfectly. Launcher_lib.dll problem started with the update to 21. Update to next 22 does also not work. Seems really to be CPU problem. I have got an AMD Athlon 3000+ which does not support SSE2. - Chrome (version 34.0.1847.131 m) gives an information that future updates are not supported. - Would be fine if Opera developer could confirm the CPU issue (or better resolve the problem if possible).
