A user at my company cant open a .out file with excel. Even when manually choosing "open with" navigating to and selecting excel.exe, Excel wont appear in the programs to choose from window as an option. Attempted go to windows explorer and %appdata% in address to rename the profile excel folder, so when reopening excel it would recreate and work off of a new excel profile folder "in case it was corrupt". Tried to associate a file type "in default programs" to force .outs to open with .csv. Tried to run the office repair tool and restart.
Reinstalled office. Still cant open a .out file in excel. Currently we have to create an excel shortcut on the desktop and actually move the .out into it, so it can be brought up in excel but this is not ideal cause she has many files that would have this to be done for so they can be saved in .csv format.
