Install Microsoft SQL Server Express
Before you install MS SQL Server Express, make sure your PC meets the DoseControl Software Platform Requirements.
Instructions are intended for DoseControl Basic License users to download and install MS SQL Server Express on a single PC.
SQL Server Overview
DoseControl software requires a SQL database. SQL is a database that resides on a centralized server and is accessed by multiple PCs. SQL is licensed to companies in many ways and you will be responsible for determining and managing your licensing. GEX does not sell or license SQL. For in-depth information about the various SQL Server types and options, please visit the official Microsoft site "Editions and supported features of SQL Server 2019".
Many Basic License users of DoseControl use Microsoft SQL Server Express, a free edition of SQL Server, for the database.
Download Microsoft SQL Server Express from the Microsoft website.

Introduction to Microsoft SQL Express (A Lightweight Version of MS SQL Server)
Microsoft SQL Express is available from Microsoft with any licensed Windows installation. A SQL Express database cannot be larger than 10 GB size; this size is sufficient for many users. You can migrate to SQL standard from SQL Express at any time by paying the license fee.
The method for installing SQL Express involves downloading the installation package from Microsoft and installing it on your PC. If you have purchased the Basic License for DoseControl then you will use the SQL Express database installed on a single PC. A SQL Express database cannot be shared between PC’s.
IMPORTANT
You must perform all the following installation and configuration steps using an account that has administrative privileges for the computer that will host SQL Server. For Basic License users, this is typically the same computer on which DoseControl is being installed.
