Quick tips for network install

  • Always install on the server first.
  • The program must be installed on each computer that will use Sage unless you are in a Terminal Services environment.
  • You can use the Network Installation Manager to install on multiple PCs simultaneously: start the installation at the first workstation, and then move on to the next.
  • The Network Installation Manager will not work over wireless networks.
  • When installing using the downloaded Sage 50 installer, the Destination folder is where the install files will be extracted; this is not the program location.
  • If operating in a domain environment, it may be necessary to set correct Windows permissions on the PeachtreeInstaller2026 folder in order to run the network installation manager
