When the Snow Inventory Agent for Windows runs a scan, you may encounter a PowerShell error that says:

_invokeOracleScanner : Cannot bind argument to parameter 'AgentPaths' because it is an empty string.

This error means that a function is expecting a parameter called AgentPaths, but it received an empty string ("") instead of a valid value.

This happens when the agent tries to run one of the Oracle-related scanners (Java, Oracle Hardware, or Middleware), but the required SNOW_AGENT environment variable is missing or not set correctly in the Windows system. Without this variable, the PowerShell script cannot locate the agent path and fails with the above error.

To fix this issue, add the required environment variable:

1. Open the Start menu and search for Edit the system environment variables.

2. In the System Properties window, click Environment Variables.

3. Under System variables, check if a variable named SNOW_AGENT exists.

4. If it does not exist:
• Click New.
• Enter the following values:
• Variable name: SNOW_AGENT
• Variable value: C:\Program Files\Snow Software\Inventory\Agent\
• Click OK to save.

5. Close all windows and restart any PowerShell sessions or services that rely on this variable.

Once the environment variable is correctly set, the Snow Inventory Agent and associated scanners should run without error.
