You must have Administrator privileges to install LinkFixer Advanced on your computer. If you do not have Administrator privileges, you will need to get an Administrator to install LinkFixer Advanced for you. 

We also strongly recommend that LinkFixer Advanced be operated only by a user with Administrative privileges, as LinkFixer Advanced requires “read-write” access to any files it will be processing. This includes files and folders located on mapped drives or other locations on your network.

LinkFixer Advanced inherits the permissions of the user account that is logged on to the machine that is running LinkFixer Advanced.
