Esko supplied SQL Express 2012 installer does not complete.


Installation fails because SQL 2012 Express needs .NETframework 3.5 whereas Windows 8.1 has .NETframework 4.5 enabled by default.


  • Make sure all current updates are installed for Windows 8.1. To check, go to Control Panel > System and Security > Windows Update > Check for Updates.
  • Do not use Control Panel > Programs > Turn Windows features on or off to enable .NETframework 3.5. Instead, use the Windows 8.1 installer DVD.
    1. At the command prompt, type Dism /online /enable-feature /featurename:NetFx3 /All /Source:<drive>:\sources\sxs /LimitAccess. Replace <drive> with the letter assigned to the local DVD drive.

    2. A successful result will show in Control Panel > Programs > Turn Windows features on or off, the following:

SQL installation should now complete.
