Office 365 problems opening 2007 and earlier files even after - Microsoft Community

i'm pc user.  installed office 365 personal , entering intense work season needs work me.

the old office 2007 kept launching reason uninstalled office 2007 today; re-started afterward.

just sure, designated office 365, 2016 versions of word, excel, , ppt defaults using start button/default programs.

i made decisions under assumption that: newer version should able open older versions.

now trying open , work on various excel files sent me.

however, 2 file types i'm struggling came in "xls" (97-2003) , file type "xlsx" (which think 2007).

somehow able save them both "xlsx" files.

but - in both cases, the way able open these files first launching new excel 2016 version , browsing files. 

i cannot open them clicking on icon directly in explorer huge convenience don't want give up.

beside steps open files, want make sure i'm doing things right won't have navigate multiple versions work done. main reason going upgrade office 365.

any issue appreciated.

thank in advance!

ps - careful sure i'm saving "this pc" aren't going cloud/one drive unless specify that.  

first, if uninstalled '2007 <after> having installed '2016, should, @ minimum, full repair of o'2016 install. uninstalling older version of program (not office) can lead unpredictable results if newer version has been installed.

if repair doesn't resolve problem, suggest doing complete uninstall of office components using ms fix-it option found @

once completed, re-install '2016
