QL-PAY 7.6.1 Installation Instructions

2026 July

QL-PAY 7.6.1 is a Windows desktop application for Quality Level - Pay Factor Analysis.

System Requirements

QL-PAY 7.6.1 requires Microsoft Windows and the Microsoft .NET Framework. The application itself targets .NET Framework 4.0. The custom installer targets .NET Framework 4.5.

Antivirus software may not recognize QL-PAY as a trusted application at first. If installation or normal file access is blocked, the user may need to allow QL-PAY in their antivirus or endpoint protection software.

Installing QL-PAY 7.6.1

1. Run the QL-PAY 7 installer executable.
2. Choose the install type.
   - Install for All Users requires Administrator privileges.
   - Install for Current User installs under the selected user profile.
3. Select the install location.
4. Choose whether to create Desktop and Start Menu shortcuts.
5. Click Continue.

The installer places the QL-PAY program files in an Exe folder under the selected installation folder. The installed application must keep its supporting DLLs, configuration file, SQLite folders, and XML6 folder together with QLPAY.exe.

First Run

When QL-PAY 7.0 is started for the first time, it checks the configured database location. If no valid database is configured, the user is prompted to select or create a QL-PAY 7 database.

Uninstalling QL-PAY 7.6.1

Run the QL-PAY 7 installer again on a computer where QL-PAY is already installed. The installer detects the existing installation and offers uninstall options.

The uninstall process removes the installed executable files and registry entries. If the user chooses a full delete option, the selected QL-PAY installation folder may also be removed. Users should back up any database, import, or export files they want to keep before uninstalling.

Notes for Existing QL-PAY 6 Users

QL-PAY 7 uses a newer database format and is not the same application package as QL-PAY 6.

To move data forward, use the QL-PAY import/export workflow where available. QL-PAY 7 includes an import option for QL-PAY 6 database data from the Sample Sets menu.
