The problem is that Adobe Flash player 11.6.602.168 installs with English language interface independent on OS setting.
The previous version 11.5.502.149 on the same OS (with the same settings) works fine, user has Norwegian interface.
How it is possible to change language from English to other one?
What OS settings are used by Adobe Flash to determine the language?
OS: Window 7+ Norwegian MUI
OS: Windows XP + Norwegian MUI
Regional settings (on both Win7 and Win XP): Norwegian
