Permission

I wonder if it there a way to assigned a permission or group of permission to all object on the database ?

please describe more details of your issue.
please always add some tags like the nav version, etc.

in nav you have the permissionsets. they are assigned to users and describe which rights a user has for the nav objects.

If all permissions are required on all objects, this can be done with ‘SUPER’ permissions, however this also includes system permissions so should only be given to system administrators.

In NAV 2016 this would be quite simple, however as Jonathan mentioned we need more details.

ok to start with, i have already installed Nav 2013 in my laptop.
then i wanted to install Nav 2015 … but when i just run installer , it rolls back,
report viewer shows this error…
