    Hi,

    i accidentally opened an .isu file with notepad. it was previously opened with an unknown application. i need this file to uninstall a certain program. when i try to uninstall the program, i get a message saying that .isu is not valid or that it is corrupted. how do i change it back to being opened by “unknown application” and not notepad?

    I didn’t find the right solution from the Internet.
