Installation Guide

Resetting read-only files

Before you install Fathom Replication on a Windows system, you should check the files in the location designated by the environment variables SytemDrive and SystemRoot to see whether any of the .dll files have the read-only bit set. If any .dll files in this directory are read-only, you must reset them to writable before installing Fathom Replication.
