Offline Vault Companion 1.0.1

Download one file and run it. This build is self-signed and untimestamped, so Windows may show a SmartScreen warning. It is not a Microsoft Store or generally trusted installer.

  1. Download and run the EXE. Open OfflineVaultCompanion-Setup-1.0.1.exe after it finishes downloading.
  2. Continue through SmartScreen. If Windows shows a warning, choose More info, then Run anyway.
  3. Approve the Windows prompt. Choose Yes when User Account Control asks for permission.
  4. Let setup finish. The installer securely installs the embedded GreenVital public certificate and app, then launches Offline Vault Companion.
