The first time I installed Microsoft office 365, it all run well, I used PPT and everything went smoothly.
Problem came when the second time I tried to use word, ppt, excel or anything, it can't verify my license, I tried every step, giving it administrator rights, compatibility, nothing worked.
When I tried to repair it, this code 30015-23 (5) came up with the text "There was a problem accessing a file. Make sure that the installer has the adequate rights and try it again" (rough translation).
I have no idea how to do that.
I'm also using a student's license.
