Installing the Assembly Connector (SIMS)

Please don’t hesitate to get in touch if you have questions. You can email us at or give us a call at 020 8506 6100.

Step 1 – Before you start

  • We recommend that the Assembly Connector is installed on your SIMS Server - or at least another server with access to your SIMS. 
  • If you run hosted SIMS, you may need to request an  External Connector from your hosted SIMS provider. If your hosted SIMS setup does not allow for an external connector to be installed, please contact us on
  • You will need administrator rights to install the connector onto the machine and start the Assembly Connector and Assembly Updater services. 
  • The local system account on the server must be able to access * URLs. If you have network level filtering (such as proxy servers or firewalls), you should add an allow rule for * URLs to the web filter on ports 80 and 443.
  • Please note: the Connector should only be installed on one machine. If you wish to switch the machines it is installed on, you must first uninstall it and then reinstall it on the new machine.
  • If you get stuck at any point during the installation please contact or 020 3897 2888 for support and, if necessary, to arrange a remote session with our dedicated support team. 

Step 2 – Sign up

  • Enter the invite code, then your email and create a password. If you do not have an invite code, please contact
  • Ensure that you have consulted and accepted the terms of service, then click Sign up
  • An email will be sent to the address you signed up with - follow the link in this email to activate your Assembly account

Step 3 – School information

  • Start typing your School name to narrow down the search, then select from the list.
  • You can also narrow down the search by entering the school postcode.
  • Select SIMS as your school’s MIS Provider from the dropdown list and press Continue.

Step 4 – Download the Installer

  • Press the Download SIMS Assembly Installer button to start downloading the connector installation file.
  • Ideally you should install the connector on a server which has SIMS installed on it. If that is not possible, you can use a server or dedicated machine with direct access to your server. Read this guide for more information on acceptable server configurations. 
  • You will need to have Administrator privileges for the server on which you install the connector.

Step 5 – Get started with the Connector Configuration

  • Please note: you may also have to install .NET 4.5 as part of the installation process (you will be prompted to do so).
  • Click Get Started to begin.

  • If you are experiencing issues with the Assembly Installer tool starting up, you can have a look at our support guide on bypassing the proxy, which may be the cause of the issue.

Step 6 - Connection

  • Click Connect to test your connection to the Platform.
  • If your school uses a Proxy server, the address (and if, necessary, credentials) should be entered on this page. We will try our best to detect your proxy settings and pre-fill this section. 
  • If you have a proxy server and the address is not found automatically, you can get this information by going to Control panel -> Network and Internet -> Internet options -> Connections -> LAN Settings.
  • If you have network level filtering (such as proxy servers or firewalls), you should add an allow rule for * URLs to the web filter on ports 80 and 443, for the local system account.

  • Once you have successfully tested the connection, click Next Step. 

Step 7 - Authentication

  • Enter the Key and Secret to authenticate your connection. These can be found by going to the Assembly platform in your browser and scrolling down to the Access Credentials area of the Connector section. 

  • Once successfully authenticated, click Next Step

Step 8 - MIS configuration

    • Forename: User
    • Surname: Assembly
    • Username: Assembly.User
    • Permission groups: add the user to these permission groups (this is an important step which ensures the User has sufficient access to pull information in to the platform):
      • Administration Assistant
      • Class Teacher
      • Personnel Officer
      • Senior Management Team
      • Third Party Reporting
      • Assessment Operator 
      • Cover Manager (This permission is only required if you will be using SchoolBooking.)
    • Password: autogenerate a password for the SIMS User. If you manually create a password for the user, it should only use alphanumeric characters (no special characters such as * / <). 
  • Enter the Connection Information:
    • Hostname: We will try our best to detect this information. If not, you should enter the database hostname. If you run SQL server under a named instance then you should enter this in the following format: hostname\instance (e.g. MIS1\SQLEXPRESS).
    • Database: We will try our best to detect this information. If not, you should enter the database name. This tends to be "sims" but may vary from school to school. 
    • Username: enter the SIMS Assembly username that you created.
    • Password: enter the SIMS Assembly password that you created. 

  • Once successful, click Finish to complete the process. 

  • If you run in to any issues at this point of the installation, please see this support article for potential causes. 
  • That's the Connector setup completed. If you plan to use an application that accesses your school's teaching groups, you'll now need to map your subjects and then authorise your app.
