NAV2013 Fatal Error During Installation - local client

Hi,

Trying to install NAV2013 RTC client on local workstation. Ran setup from a copy of the NAV2013 stored on the file server - got the following errors in the installation log:

User has local admin permissions on her machine.

I then copied the contents of the NAV2013 installation DVD files from the directory that supposedly couldn't be read on the server to the local machine and ran SETUP from there. RTC client installed perfectly.

Any ideas on why we can't run SETUP successfully from a shared location on the server?
