An exit code 1603 indicates a fatal error during installation. This usually happens if:
To confirm the silent install worked without opening the app, you can check the Registry or the file system: C:\Program Files (x86)\EPSON\Epson Scan 2\
Yet, challenges do exist. One common pitfall is the presence of older versions of Epson Scan or other imaging software. A silent installation may fail if a prerequisite—such as the Epson Scanner Common Module or a specific version of the .NET Framework—is missing. Administrators must thus treat the silent install as part of a larger task sequence, deploying dependencies first. Another challenge is 32-bit vs. 64-bit architecture; deploying the wrong MSI package silently will result in a quiet failure, requiring the administrator to audit logs to find the error. Finally, on modern systems with User Account Control (UAC), even a silent install must be executed with elevated privileges, meaning the deployment script must be run under a system context rather than a standard user context. epson scan 2 silent install
In these systems, you can create a package that runs the extracted Setup.exe with the /SI -sms /Nodisp arguments. Ensure the package has access to all the extracted files as the installation may depend on them.
During deployment, verify that msiexec.exe or Setup.exe processes trigger under the System context and close without throwing an error code. An exit code 1603 indicates a fatal error
Locate the generated configuration file (often named EScan2.ini or containing the scanner's MAC/IP address).
Ensure your deployment tool is running the script as "System" or an Administrator user. A silent installation may fail if a prerequisite—such
Ensure you are using the latest drivers from Epson. Older drivers might trigger a Windows Security prompt asking if you "Trust this publisher," which will hang a silent install indefinitely. Summary for IT Admins
