Installation Troubleshooting - Logging

All Verigio products are distributed as MSI installer files that allow you to install and uninstall the products via Windows "Add Remove Programs" or "Apps & features". These installer files accept standard parameters that can be viewed by launching the MSIs from the command line with the "/?" switch.

Installer Logs

1. To produce installer logs, the MSI can be launched with the "/lvx* log_file_path_name" parameters.
Example: MultiPortForwarder-6.43-x64.msi /lvx* c:\install.log

2. In addition to application files, Verigio products install device drivers that perform network traffic processing and output additional information during installation and uninstallation into the SetupAPI log c:\Windows\Inf\setupapi.dev.log. To enable Verbose output from all installers (not just Verigio products) into the SetupAPI log, set the following registry value:
Registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup
Value name: LogLevel
Value: 0x00007070
