Installing the Server

 

The Server is the computer that stores the primary MLS 2026 data files.

It may be:

a dedicated server computer

or one workstation within a small business network

All client workstations will connect to this computer to access the MLS 2026 system.

The server installation must always be completed first.


Important Note For Existing MLS 12 Installations

If your system already has:

MLS12s

installed and operating properly, then:

👉 you do NOT need to reinstall the server software.

MLS 2026 client workstations will operate correctly against:

the existing MLS12s database structure

the existing auto updater service

This allows existing installations to transition smoothly to MLS 2026 without rebuilding the server.

In these cases:

only the MLS 2026 client software may need to be installed or updated

existing data and processing remain intact


New Server Installation

MLS 2026 server software is installed using:

MLS2026s.exe

This installation creates:

the main MLS2026s folder

database folders

support folders

server utilities

the automatic updater service

The server installation itself does NOT create your operational data.

It installs the system structure necessary for operation.


Installation Procedure

Step 1 — Download The Installation File

Download:

MLS2026s.exe

to the computer that will function as the server.

You may temporarily place the file:

on the desktop

in Downloads

or any convenient location


Step 2 — Start The Installation

Double click:

MLS2026s.exe

to begin installation.

Windows security may ask for confirmation before continuing.


Step 3 — Follow The Installation Prompts

The installer will guide you through the process automatically.

Answer the displayed questions as prompted.

For support and compatibility purposes, we strongly recommend accepting:

the default installation folders

the default installation structure

The normal installation folder is:

\MLS2026s


Step 4 — Complete The Installation

When installation completes, the server software will have created:

the primary program folders

database structure

update services

support utilities

The automatic updater service will also be installed into Windows.

This service performs:

automated updates

background processing

scheduled maintenance activities

communication with approved third-party integrations


Pre-Configured Data

If you are starting a completely new installation and do not have previous MasterLink data to import, you may choose to use the supplied pre-configured data.

This may include:

automotive labor glossary information

general ledger defaults

payroll tax tables

standard accounting structures

predefined operational settings

This can greatly simplify initial setup.


Importing Existing Data

MLS 2026 can import data from current versions of:

MasterLink Shop Writer

Your existing data should already reside:

on the current server

or in a known backup location

You should know the path to the current data folder before beginning.


Using Data Manager To Import Data

After the server software installation completes:

Start Data Manager

Open:

DataManager

Your initial login credentials are:

User:

LINK

Password:

MASTER


Import Procedure

Step 1 — Create New Databases

From the menu:

Files → Create New Databases


Step 2 — Import Existing Data

From the Import menu:

select the version you are currently using

select the path to the existing data folder

The system will then import your information directly into the MLS 2026 database structure.


Step 3 — Rebuild Indexes

After importing:

Files → Index

Select:

Select All

Then begin the indexing process.

This rebuilds all indexes for the imported data.


Step 4 — Authorize The System

From the menu:

Edit → Authorize

You will be prompted for your serial number.

Use:

the original 5-digit serial number assigned to your business

⚠️ Do NOT perform authorization using an incorrect serial number.


Installation Complete

At this point:

the server installation is complete

the databases are ready

the updater service is installed

workstations may now be configured


If You Are NOT Importing Existing Data

If you are starting with new empty databases:

omit the Import step

omit the Index rebuild step after import

The system will already contain clean database structures.


Important Warning

If you make a mistake during installation:

❌ DO NOT uninstall and reinstall the software.

Unnecessary uninstall/reinstall procedures often create:

additional configuration issues

broken paths

permissions problems

update conflicts

Most installation issues can be corrected quickly without reinstalling the software.
