Maventa Connector

Download

Maventa Connector is a Windows service that moves invoices and other electronic documents between local folders and the Maventa service. It is used to integrate Maventa with ERP systems that read and write files instead of calling the API directly.

Download Maventa Connector 2.1.9713.28334

Latest version 2.1.9713.28334, released 14 August 2026.

Maventa Connector 2.1 requires Microsoft .NET Framework 4.8.1, which can only be installed on Windows 10 (version 21H2 or later), Windows 11, or Windows Server 2022 or later. Make sure it is installed before running the installer, and run the installer as administrator.

What’s new in version 2.1

Version 2.1 focuses on security hardening in line with the EU Cyber Resilience Act (CRA).

Built on .NET Framework 4.8.1 (previously 4.6.1) — a currently supported and security-maintained runtime. This also raises the Windows version required.
Your API keys are encrypted at rest. They are no longer stored in plain text in config.xml, but encrypted with Windows data protection and tied to the machine.
Runs with fewer privileges. The background service runs as NetworkService instead of LocalSystem, and the Connector application itself runs as a normal user — so you no longer get a UAC prompt every time you open it. Starting and stopping the service from the Connector still works as before.

Upgrading to version 2.1

Check your Windows version first. .NET Framework 4.8.1 cannot be installed on Windows 8.1, Windows Server 2016 or Windows Server 2019, so Connector 2.1 will not run on those machines. Update Windows to a supported version before upgrading.

Run the installer as administrator. It changes the service account and adjusts file and service permissions, which requires elevation.
Complete the one-time administrator step. The first time you open the Connector after the update, it notices that the background service still runs under the old account and asks whether to finish configuring it. Answer Yes and accept the UAC prompt. This happens only once.
Check the rights on network folders. Because the service now runs as NetworkService, your OUT, IN and BACKUP folders must allow access for that account. This is granted automatically for folders you own. For folders on a file server, your administrator may need to grant NetworkService — or the computer account — read and write access. A missing grant usually appears in the log as “IN directory does not exist” for a folder that clearly does exist.

If you answer No to the one-time question, or if you are not an administrator on the machine, open an administrator command prompt in the Connector install folder and run: MaventaService.exe --reconfigure

Until that is done, the Connector cannot save its settings and invoice transfer does not resume.

Your existing settings are migrated automatically and you do not need to log in again. Two things to note afterwards: configuration files are no longer portable between machines, because the API keys are encrypted and machine-bound, and the invoices-sent counter that was visible in the UI has been removed.

Frequently asked questions

Question: Installer stops with error like “service already exists”, what to do?

The old Connector service called “MaventaService” already exists and needs to be removed manually. Follow these steps:

Run (as as admin) the command “services.msc” or browse to the Windows Services Management. See if “Maventa Connector Service” is listed. If it’s running, stop it.
Open an admin command prompt and run the command: sc DELETE MaventaService
Reboot computer might be a good idea here
Launch new Connector installer which should now be able to pass

Question: Which operating systems are supported?

Connector 2.1 requires .NET Framework 4.8.1, so it runs on these operating systems:

Windows 10, version 21H2 or later
Windows 11
Windows Server 2022 or later

Older operating systems — including Windows 7, Windows 8.1, Windows Server 2012 R2, Windows Server 2016 and Windows Server 2019 — cannot install .NET Framework 4.8.1 and cannot run Connector 2.1. Update Windows to a supported version before upgrading. If that is not possible right away, contact Maventa customer support about staying on an older Connector version in the meantime.

In any case, you should not be using an operating system that is no longer supported by Microsoft and expect it to keep working properly forever. For security reasons, always use a supported operating system that still receives security updates from Microsoft.
