Removing a proxy agent can fail if Windows Installer Logging is enabled.
When you try to uninstall a proxy agent from the Windows Control Panel, the uninstall fails and you see the following error:
Error opening installation log file. Verify that the specified log file location exists and is writable
This can occur if Windows Installer Logging is enabled, but the Windows Installer engine cannot properly write the uninstallation log file. For more information, see Microsoft Knowledge Base article 2564571.
- Restart your machine or restart explorer.exe from the Task Manager.
- Uninstall the agent.
