Did you try deleting all the temporary files of IE? (cache and everything)
Yes tried and deleted all files.
Thanks.
Have you checked your version (and settings) of IE are certified for use with your OBIEE version?
***Moderator note (Timo): @HKVOOSA-Oracle it's rude to delete the question after other users have already spend time helping you. Please don't act like this again!***
