Download QuerySolv Installer with Free Trial The same installer serves the trial, the Free edition and the licensed editions; the key you install decides which one you are running.
System requirements
Windows
Windows Server 2008 through 2025, or Windows 7 through 11. The service and its control panel are native Windows programs with no runtime framework to install.
A database
Nothing extra for the built-in SQLite database. If you prefer a database server you already run: MySQL 5.5.3 or later, MariaDB 5.5 or later, or Microsoft SQL Server 2005 or later.
Administrator rights
Installing, starting and stopping the service and running the control panel need an administrator account on the machine.
A free network port
The service listens for HTTPS on port 443 by default, with plain HTTP on port 80 available but switched off. Both are configurable.
Browsers
Agents use any current browser. Requesters can use any browser at all; the portal works with scripting off and stays presentable back to Internet Explorer 11.
Hardware
No particular hardware is called for. The same installer works on a retired desktop for a small team or on a current server for a large one.
Installing
- Run the installerFrom an administrator account; accept the elevation prompt when Windows asks. The installer places the programs, creates the data folder and registers the Windows service for automatic start.
- Start the serviceFrom the control panel's Start Server button, the Windows Services console, or an elevated prompt. First start writes the configuration, generates a self-signed certificate and creates the database.
- Follow Quick StartOpen the control panel from the Start menu. Quick Start walks through the database, the web interface, the first department, its mail and the first agent.
- Send a test requestThe control panel links to the request portal and the agent sign-in page. Raise a request from one, answer it from the other.
The service runs for 30 days with every Professional edition feature and unlimited agents (clustering needs a High Availability edition key). The control panel shows the days remaining. When the trial ends, the service stops serving until a key is installed: choose Install License in the control panel, pick the key file and restart. Nothing is reinstalled and no data moves.
Upgrading an existing installation
- Take a backupThe database, the configuration file and the certificates folder. Attachments live inside the database, so there is no file share to copy.
- Stop the service, run the new installer, start the serviceThe data folder, with your database and configuration, is kept apart from the program files and is left alone. The service checks and migrates its own database schema when it starts, so there is no separate upgrade utility and nobody needs to clear a browser cache.
- Pick a quiet momentRestarting the service signs agents out.
A license key covers every build released during its update period. A build released after that period may ask for a newer key, so check the release date against your key before you upgrade a licensed installation. The licensing page explains the update period.
Removing it
Stop the service, uninstall the package from Windows' list of installed programs, and then delete the data folder if you do not want to keep the database, the logs and the configuration. If you only want to stop evaluating, that is the whole procedure.
