 There is no need for an expensive license, the Express edition which is freely available will work fine for most small countries. If you don't have already a commercial license download the free version [[https://www.microsoft.com/en-us/download/details.aspx?id=29062|MS SQL Server Express]]. Any of the files would have the required minimal database engine but might has well download the 64bit full version called //ENU\x64\SQLEXPRADV_x64_ENU.exe//. Double click and follow through the installation. Choosing the default values is a good start and reboot the system when done.

 ==== Install .NET Framework ====
-Install [[https://www.microsoft.com/en-us/download/details.aspx?id=48130|.NET 4.6 Framework]] by downloading the web installer and running it, of course a good Internet connection will be required.
+The projects in the whole solution target either 4.6, 4.6.1 and 4.6.2. The migration to target 4.8 in each project is on-going. But the compiled solution runs fine in the default .NET that comes with the operations system and there should be no need to install another .NET version.

 === Automate daily SQL database exports ===
-This unfortunately can not "easily" be done with SQL Server Express (free edition), though there are ways. Here the steps outlined are with a licensed version of SQL Server.
+There are two ways to achieve this:
+  * The expensive paid version of Microsoft SQL Server can easily produce nightly backup plans from the UI.
+  * The free version of Microsoft SQL Server Express does not support this feature. However, it is not difficult to produce a script to do the backup and execute the script using the Windows Task Scheduler. This is the method used in most deployment of Pacific EMIS using a custom script on the server.
