Using the Zip File

Note If you are upgrading, please do not manually execute upgrade SQL scripts - install the new release, browse to the site, and Gemini will auto upgrade for you.



The zip file download contains both the Gemini web application and the sample database to get you going.

The following must be present on your Windows Server. You can choose to have your IIS Web Server and SQL Server on the same machine or each running on different machines.

  • Microsoft .NET Framework v4.7.2 or above
  • SQL Server

If you cannot confirm, or do not understand any of the above items, then either contact us or your IT administrator.

If you have not downloaded Gemini, please click here to download the latest release.



Note Right click on the file then select Properties and click Unblock.

Unzip Gemini and open the manual install folder.

Step 1 - Check Pre-requisites

Please check here if you have everything ready for the installation process.

Step 2 - Unzip

Unzip the Gemini zip file and you should see the contents as follows:

Step 3 - Create Application Pool

First you should create an application pool for your site. In IIS right-click, and add an application pool.

Name the application pool. Set the .NET Framework to v4.0 and Managed pipeline mode to Integrated.

Note If you are using the ticketing or scheduled reporting features of Gemini make sure that app pool is set to be "Always On".

Step 4 - Create Web Application

In IIS right-click and add Gemini as an Application:

You will need to give your Gemini application a name such as "Gemini". This will mean Gemini will be accessible via https://servername/Gemini.

Select the Gemini application pool:

After the Gemini web application has been created you will see this:

We recommend that you apply a SSL Certificate to your site, especially if it is open to a public network. See your network administrator if you do not know how to do this.

Step 5 - Create SQL Database

Create a SQL Server database that will be used by Gemini.

It is advisable to use SQL Server Standard or Enterprise editions. Gemini will run with SQL Express but it is not recommended and not supported for production instances.

Where possible use SQL or Mixed (SQL and Windows) Authentication and make a note of your SQL Server user credentials (required for next step). Ensure your SQL user has DBO permissions in the new database.

Step 6 - Edit Web.config

Right-click on the Gemini Web Application in IIS and select the Explore option:

Edit the web.config file and put in the correct SQL Server user credentials:

Save the web.config and Gemini should now be setup.

After installation you can navigate to the Gemini web application using your browser (e.g. http://myserver/gemini).

If you see something like the above, then Gemini has been installed correctly.

Login Credentials Username is "manager" and password is "manager"

Step 7 - Set Folder Permissions

For complete administrative control, Gemini requires write access to the following THREE FOLDERS that are located where you installed Gemini:

  • Right click the App_Code folder, select Security tab, allocate Modify/Full Control permissions to the EVERYONE group
  • Right click the App_Data folder, select Security tab, allocate Modify/Full Control permissions to the EVERYONE group
  • Right click the Assets folder, select Security tab, allocate Modify/Full Control permissions to the EVERYONE group
