Can't install NetBackup 7.5 with UAC turned on
I need to install NBU 7.5 on a Windows 2008R2 server. But when I run the installer (even when I select "Run as Administrator") the install fails. What happens is the setup.exe runs but disappears and runs forever and nothing happens. I then need to kill the task in task manager to run setup again.
I see in the NBU install guide it asks me to "log on as the official administrator". But how can I do that? I can turn off UAC but I don't want to reboot it because people are using the server.
Note: To install NetBackup on Windows 2008/Vista and
Windows 2008 R2/Windows 7 UAC-enabled environments,
you must log on as the official administrator. Users that are
assigned to the Administrators Group and are not the official
administrator cannot install NetBackup in UAC-enabled
environments. To allow users in the Administrators Group
to install NetBackup, disable UAC.
