Installing WiltonDB - wiltondb/wiltondb GitHub Wiki

On this page:

Window version requirements

WiltonDB can be installed onto a Windows Server (2016 or later) or onto desktop Windows 10 or 11. Wilton DB only supports x86_64 (also known as AMD-64) processor architecture.

Installation prerequisites

WiltonDB requires the Microsoft Visual C++ Redistributable as a prerequisite to the installation.

Download the latest version of the redistributable from this (direct) link: VC_redist.x64.exe and run it:



Running the installer

WiltonDB requires Administrator priviliges to perform the installation:





Check that WiltonDB is added to the list of installed programs:


Check that WiltonDB Windows service was successfully registered and has started:


Using GUI configuration tool

Configuration tool can be opened automatically when installation is completed:


It can be used to inspect and change database settings. To use this tool after the installation you can pin it to Windows taskbar using right-click context menu.

Installation troubleshooting

In case of problems during the installation it may be rolled back automatically:



Usually problem details will be available in system Event Viewer under "MsiInstaller" or "PostgreSQL" event source:


Database cluster is created automatically during installation in <install_dir>/data directory inside the installation directory. In case when data directory already exists on this path (for example: remained there from a previous installation), cluster creation is skipped and the service attempts to use existing data directory.


If service startup error is displayed, cancel the installation, rename or remove existing data directory and rerun the installer.

When system Event Viewer does not provide enough information, it is possible to run the installer with verbose logging. To do that open the Administrator Command Prompt and run the following:

msiexec /i wiltondb3.3_2.4.1.msi /L*V c:\tmp\install_log.txt

Inspect the generated install_log.txt for possible erors. For example the following error will be recorded if Microsoft Visual C++ Redistributable is not installed:
