Nothing. You need to delete RunAs.
Interactive User is for Interactive user. Absense of anything is the launching user.
Question
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\%APPID% /v RunAs /d %USERDOMAIN%\%USERNAME%
if I want to set DCOM properties (the identity tab) from "%USERDOMAIN%\%USERNAME%" to "the launching user", is it possible and how to do that? please help.
