Note: If your Windows version supports it, the Doors.NET installer will install SQL Express 2019 on new installations. Otherwise there are three available options:
You can proceed by selecting an existing SQL Server on your network.
You will need to manually install SQL Server/SQL Server Express 2016/2017 and then re-run the install.
Install Doors.NET v4.4.0 (which will install SQL 2016) and then re-run the latest Doors.NET installer.
1.6 Additional PC Requirements
Hardware - 64-bit PC microprocessor
Operating System - 64-bit OS
Windows 11 or Windows 10 LTSC or Server 2016 or greater
- Server 2016 or greater
- SQL Server/SQL Express 2016 or greater
- Microsoft .NET Framework v4.8.0 or greater. This version of .NET Framework is required to take advantage of all enhancements implemented in Doors.NET v6.0.0.8.
2.0 Operating System Compatibility
Important Note: To successfully run Doors.NET you should ensure that the Windows operating system on the host PC is fully updated and still supported by Windows and not End of Life - this ensures the operating system is still receiving important security and performance updates.
Windows 10 LTSC and Windows 10 Enterprise LTSC (Long Term Servicing Channel) will continue to receive important Windows updates for several more years but the EOL date is dependent on the specific version that you have installed.
To find out your specific installed version of Windows:
- Type WINVER into the Windows search field.
- Press <ENTER>
- The specific version of Windows will be displayed.
You should use the official Microsoft website to find out the official End of Life (EOL) date for your specific version of Windows.
The following Windows operating systems are compatible with Doors.NET v6.0.0.8 and v5.4.0.8.
- Windows Server 2025 (x64)
- Windows Server 2022 (x64)
- Windows Server 2019 (x64)
- Windows Server 2016 (x64)
- Windows Server 2012 and 2012R2 *
- Windows 11 (x64) - all versions
- Windows 10 LTSC (x64) - all versions
- Windows 10 (x64) - all versions *
All other operating systems are NOT SUPPORTED
* The standard version of Windows 10 and Windows Server 2012 and Server 2012R2 are compatible with Doors.NET v6.0.0.8 and v5.4.0.8. However Microsoft has ended support for these operating systems - therefore Keri Systems does not recommend using them for running Doors.NET.

- Windows Server 2012 and 2012R2 End of Life - 10th October 2023
Doors.NET Important Software Notes:
Before installing Doors.NET you should ensure that the host PC is updated with all the latest Windows updates.
The host PC should have a Solid State Drive (SSD) and not a Hard Disk Drive (HDD) - the installation time will be considerably longer if the host PC has a hard disk drive and overall PC performance will be slower.
Doors.NET v5.4.0.8 is the last version of Doors.NET that supports PXL and Entraguard controllers. These controller types are not end-of-life, ongoing support for these controllers will be in Borealis.
Doors.NET series 4 and later versions are not compatible with Aimetis Symphony and Panasonic Video as these systems are dependent upon an older version of Microsoft .NET Framework software. This is likely true for other, older video systems as well.
Keri has ended support for ASSA Wi-Fi/PoE locking products.
The Visual Doors client is installed effective from series 4. It is not available for use with older versions of Doors.NET.
