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. Prefer x86 when the token CSP is 32-bit (ePass2003). Use x64 or ARM64 only when the middleware ships a matching provider.

  2. Client: run the MSI (or msiexec /i EGKits.EtaSigningAgent-{version}-win-x86.msi).

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

  4. Silent: append /qn /norestart. Accept the installation terms in the wizard when installing interactively.

After install

  1. Edit appsettings.json under Program Files\EGKits\EtaSigningAgent (or Program Files (x86) for the x86 package) 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.

Upgrade

  1. Download the newer MSI. Installing a different architecture replaces the previous one (they share an UpgradeCode).

  2. Run the new MSI. Operator-edited appsettings.json is not overwritten.

  3. Restart the tray agent or Windows service after the upgrade if it does not restart by itself.

Uninstallation

  1. Open Windows Settings → Apps and uninstall EGKits ETA Signing Agent, or msiexec /x the MSI /qn /norestart.

  2. The installer stops the tray process and removes the Windows service and Start Menu shortcut.

  3. appsettings.json is removed with the program folder; token certificates in Windows remain. Logs under %ProgramData%\EGKits\EtaSigningAgent are kept.
