Setup

Installation

Before you install

  1. Install the token middleware so the certificate appears in Personal Certificates.

  2. Create or confirm a dedicated EGKits service account with Sign Invoices permission.

  3. Decide client (workstation tray) vs server (Windows service) deployment.

Install

  1. Download the official MSI from this page.

  2. Client: msiexec /i EGKitsEtaSigningAgent.msi

  3. Server: msiexec /i EGKitsEtaSigningAgent.msi INSTALLMODE=server

After install

  1. Edit appsettings.json under Program Files (x86)\EGKits\EtaSigningAgent as administrator.

  2. Set BackendBaseUrl, Tenant, credentials, certificate thumbprint, and optional TokenPin.

  3. Restart the agent (tray) or Windows service after saving settings.

Configuration

  1. Prefer Agent:CertificateThumbprint to select the token certificate.

  2. For ePass2003-style tokens, set Agent:TokenPin and optional Pkcs11ModulePath.

  3. Client-side signing: keep LocalBridgeEnabled true; farm hosts should disable the bridge.

Troubleshooting

  1. Check %ProgramData%\EGKits\EtaSigningAgent\logs\agent-YYYYMMDD.log for startup and signing errors.

  2. If the PIN dialog still appears, verify PKCS#11 module path (32-bit DLL for the x86 agent).

  3. Confirm the web app SigningAgentDownloadUrl / ETA configuration points at this official MSI.
