Avira mailguard removal triggered Setup.exe.....

Got a little lost yesterday. I was removing a feature from Avira 9 PE I did not want any more. Which was the mailguard feature. When I unselected it. It triggered Setup.exe and I got a little lost. I kept clicking on “ok” with D+ and it just kept going on and on with pop ups. Finally I selected installer/update with D+ and all the pop ups went away. My question is though. Would Setup.exe fall under installer/updater with D+?

No it would not fail, installer/updater can be used for uninstalling aswell as installing.
