How To Find GUID Of Installed Software PowerShell

Finding the GUID of installed software using PowerShell is a common task for system administrators and software developers. This article, brought to you by CONDUCT.EDU.VN, offers multiple methods to efficiently retrieve a software’s GUID, ensuring proper software management. Learn about the product code identifier and Windows Installer details for seamless troubleshooting.

1. Understanding the Importance of the ProductCode GUID

The ProductCode, a GUID (Globally Unique Identifier) composed of numbers and uppercase letters, is unique to each Windows Installer package (MSI). This uniqueness prevents conflicts by ensuring that two software products with the same ProductCode cannot be installed on the same machine. Attempting to do so will result in an error message, highlighting the importance of the ProductCode in software management. Understanding how to find this ProductCode is crucial for various administrative tasks, including software uninstallation, repair, and verification. This article delves into different methods to locate the ProductCode using PowerShell, ensuring you have the necessary tools to manage your software effectively.

2. Locating the ProductCode Property Within the MSI File

The most straightforward method to find the ProductCode is by directly examining the MSI file. If you have access to the MSI file, you can use an MSI editor tool to open it and navigate to the “Property” table. The ProductCode property within this table provides the unique identifier for the Windows Installer package. This method is particularly useful when you need to identify the ProductCode before installing the software or when troubleshooting installation issues.

3. Finding the ProductCode Using Uninstall Registry Keys

Another method to find the ProductCode involves searching the Uninstall Registry keys. This approach requires navigating through the Windows Registry, which can be more complex than using an MSI editor. However, it is a valuable technique when you do not have direct access to the MSI file.

3.1. Navigating to the Uninstall Registry Keys

The Uninstall Registry keys can be found under several registry hives, depending on whether the software is a 64-bit or 32-bit installer and whether it is installed per-machine or per-user:

x64-bit installer, per-machine based installation:

HKLMSOFTWAREMicrosoftWindowsCurrentVersionUninstall

x86-bit installer, per-machine based installation:

HKLMSOFTWAREWOW6432NodeMicrosoftWindowsCurrentVersionUninstall

x64-bit installer, per-user based installation:

HKCUSOFTWAREMicrosoftWindowsCurrentVersionUninstall

x86-bit installer, per-user based installation:

HKCUSOFTWAREWOW6432NodeMicrosoftWindowsCurrentVersionUninstall

3.2. Identifying the ProductCode

Within these registry hives, the details of each installed software product are stored in a subkey identified by the ProductCode. By navigating to the appropriate subkey, you can find the ProductCode and other relevant information about the software.

4. Utilizing VBScript to Find the ProductCode

VBScript offers another method to retrieve the ProductCode. The WiLstPrd.vbs script, included in the Windows SDK Components for Windows Installer Developers, can be used to retrieve registered products and product information on the local device.

4.1. Executing the VBScript

To retrieve the ProductCode of a specific software product using VBScript, you can run the following command from a command prompt:

cscript "WiLstPrd.vbs" <productname> | findstr ProductCode

Replace <productname> with the name of the software product you are interested in.

4.2. Interpreting the Results

The script will output the ProductCode of the specified software product. This method requires the Windows SDK to be installed and the script to be executed with administrative permissions.

Alternative Text: Retrieve ProductCode with VBScript command line example and the resulting output showing the ProductCode.

5. Leveraging PowerShell to Find the ProductCode

PowerShell provides a powerful and efficient way to find the ProductCode of installed software. By using the Win32_Product class in Windows Management Instrumentation (WMI), you can access information about all Windows Installer packages.

5.1. Using Get-WmiObject to Retrieve Software Information

The Get-WmiObject cmdlet allows you to query WMI classes. To retrieve the ProductCode and name of all installed software, you can use the following command:

Get-WmiObject Win32_Product | Format-Table IdentifyingNumber, Name

This command will output a table with the ProductCode (IdentifyingNumber) and name of each installed software product.

5.2. Filtering Results to Find a Specific Software’s ProductCode

To find the ProductCode of a specific software product, you can use the Where cmdlet to filter the results. For example, to find the ProductCode of a software named “ExampleSoftware,” you can use the following command:

Get-WmiObject Win32_Product | Where Name -eq 'ExampleSoftware' | Format-Table IdentifyingNumber, Name

Replace 'ExampleSoftware' with the actual name of the software you are interested in. This command will output the ProductCode and name of the specified software product.

5.3. Enhanced PowerShell Script to Retrieve ProductCode

For a more robust solution, consider a PowerShell script that handles potential errors and provides clear output. Here’s an example:

try {
    $softwareName = Read-Host "Enter the name of the software"
    $software = Get-WmiObject Win32_Product -Filter "Name like '$softwareName'"

    if ($software) {
        Write-Host "Product Name: $($software.Name)"
        Write-Host "Product Code: $($software.IdentifyingNumber)"
        Write-Host "Version: $($software.Version)"
        Write-Host "Vendor: $($software.Vendor)"
    } else {
        Write-Warning "Software '$softwareName' not found."
    }
} catch {
    Write-Error "An error occurred: $($_.Exception.Message)"
}

This script prompts the user for the software name, retrieves the software information, and displays the ProductCode, name, version, and vendor. It also includes error handling to manage potential issues.

5.4. PowerShell Script with Detailed Logging

To enhance the script further, consider adding logging capabilities. This can be invaluable for auditing and troubleshooting.

try {
    $logPath = "C:LogsSoftwareProductCode.log"
    $softwareName = Read-Host "Enter the name of the software"

    # Log the start of the script
    "$((Get-Date).ToString()) - Starting script to find ProductCode for software: $softwareName" | Out-File -FilePath $logPath -Append

    $software = Get-WmiObject Win32_Product -Filter "Name like '$softwareName'"

    if ($software) {
        Write-Host "Product Name: $($software.Name)"
        Write-Host "Product Code: $($software.IdentifyingNumber)"
        Write-Host "Version: $($software.Version)"
        Write-Host "Vendor: $($software.Vendor)"

        # Log the software details
        "$((Get-Date).ToString()) - Product Name: $($software.Name)" | Out-File -FilePath $logPath -Append
        "$((Get-Date).ToString()) - Product Code: $($software.IdentifyingNumber)" | Out-File -FilePath $logPath -Append
        "$((Get-Date).ToString()) - Version: $($software.Version)" | Out-File -FilePath $logPath -Append
        "$((Get-Date).ToString()) - Vendor: $($software.Vendor)" | Out-File -FilePath $logPath -Append
    } else {
        Write-Warning "Software '$softwareName' not found."
        # Log that the software was not found
        "$((Get-Date).ToString()) - Software '$softwareName' not found." | Out-File -FilePath $logPath -Append
    }

    # Log the end of the script
    "$((Get-Date).ToString()) - Script completed." | Out-File -FilePath $logPath -Append
} catch {
    Write-Error "An error occurred: $($_.Exception.Message)"
    # Log the error
    "$((Get-Date).ToString()) - Error occurred: $($_.Exception.Message)" | Out-File -FilePath $logPath -Append
}

This version logs the start and end of the script, the software details if found, and any errors that occur.

5.5. Exporting Results to CSV

For reporting and analysis, exporting the results to a CSV file can be useful. Here’s how to modify the script:

try {
    $softwareName = Read-Host "Enter the name of the software"
    $software = Get-WmiObject Win32_Product -Filter "Name like '$softwareName'"

    if ($software) {
        $output = @{
            ProductName = $software.Name
            ProductCode = $software.IdentifyingNumber
            Version = $software.Version
            Vendor = $software.Vendor
        }

        $output | Export-Csv -Path "C:LogsSoftwareDetails.csv" -NoTypeInformation
        Write-Host "Software details exported to C:LogsSoftwareDetails.csv"

    } else {
        Write-Warning "Software '$softwareName' not found."
    }
} catch {
    Write-Error "An error occurred: $($_.Exception.Message)"
}

This script creates a hashtable with the software details and exports it to a CSV file.
