So, what was wrong with the answer the other forums gave you?
Im having problems opening some problems like divx installer. They would not open even when i used the administrator account to try. Nothing pop up at all. I tracked the programs using task manager but it only showed the programs hanging at a specific memory usage and disappearing.
Another problem is that programs that support Chinese would change immediately to chinese despite being as default english. All my language settings are set to English, as well as the system locale, which was set to Chinese at first but changed back to English. Basically, the whole question is specified at this other forum : http://www.sevenforums.com/software/84134-programs-disappearing-after-few-secs-opening.html . Hope u guys can help me. Thx ~
