Specify verbose log files for ClickOnce deployments

  • Article

ClickOnce maintains activity log files for all deployments. These logs document details pertaining to installing, initializing, updating, and uninstalling a ClickOnce deployment. To increase the detail that ClickOnce writes to these log files, use Registry Editor (regedit.exe) to specify the verbosity level.

Caution

If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall the operating system. Use Registry Editor at your own risk.

The following procedure describes how to specify the verbosity level for ClickOnce log files for the current user. To reduce the level of verbosity, remove this registry value.

To specify verbose log files

  1. Open Regedit.exe.

  2. Navigate to the node HKEY_CURRENT_USER\Software\Classes\Software\Microsoft\Windows\CurrentVersion\Deployment.

  3. If necessary, create a new string value named LogVerbosityLevel.

  4. Set the LogVerbosityLevel value to 1.
