In Microsoft Intune Win32 App Detection Rules are used to determine the presence of a Win32 App. The detection rules ensure that app installation only start if it’s not installed yet. A Win32 App can have multiple detection rules and all detection rule must be met to detect the application. However in the case of an Uninstall, only one detection rule should match in order to trigger uninstall.
In this article, we will discuss about different detection rules available in Microsoft Intune for Widows Apps (Win32).
Win32 App Detection Rules
Let’s have a look at detection rules available in Microsoft Intune. Open Microsoft Intune admin center and navigates to Apps > Windows > Windows apps, Select any Win32 app and click on Properties > Detection rules to open Detection rules blade.
Note: You have to create a Win32 app if you don’t have any. Check this article if you want to know how to deploy a win32 app.
The following detection rule formats are currently available in Microsoft Intune.
Manually configure detection rule: This detection rule format allow Intune administrator to specify a detection rule based on MSI product code, file or folder existence, file version, registry key or registry value.
Use custom detection rules: This detection rule format allow Intune administrator to specify detection rule using custom script.
Manually Configure Intune App Detection Rule
Let’s understand how to manually configure Intune detection rules in details. This detection rule format provides three type of detection rules which are MSI , File & Registry.
MSI Product Based Win32 App Detection Rules
This detection rule detect application installation based on MSI product key or version check. When you choose this rule type, you have two settings:
- MSI product code: This property allow administrator to configure MSI product code to detect the installation of App. When you use this rule type with an MSI, the MSDI product key populated automatically.
- MSI product version check: This property allow administrator to configure an additional check that is specific version of MSI product code to detect the application.
Example of MSI product detection:
Check for app existence based on MSI product code
Check for app existence based on product code and version
Client side activities:
Each activities of Win32 app installation process are logged in Intune Extension Manger log file located at C:\ProgramData\Microsoft\IntuneManagementExtension\Logs folder. That includes downloading policies to detection and installation. We will focus on policy and detection rule in this article.
The below snippets from IntuneExtensionMnager.log show the details of policy received by client which include the details of detection rules.
Get policies = [{"Id":"4c153c53-913e-4a75-92b1-27e53ca03876","Name":"WinZip 26.0","Version":1,"Intent":3,"TargetType":2,"AppApplicabilityStateDueToAssginmentFilters":null,"AssignmentFilterIds":null,"DetectionRule":"[{\"DetectionType\":1,\"DetectionText\":\"{\\\"ProductCode\\\":\\\"{CD95F661-A5C4-44F5-A6AA-ECDD91C2413B}\\\",\\\"ProductVersion\\\":\\\"26.0.14610\\\",\\\"ProductVersionOperator\\\":1}\"}]","InstallCommandLine":"msiexec /i winzip260-64.msi /qn INSTALLDIR=\"D:\\Program Files\\WinZip26\"","UninstallCommandLine":"msiexec /x \"
The Win32 App Detection rules phase records the evaluation of each detection rule. The DetectionType 1 represent MSI based detection rule in above snippets. You can see further the application detection was failed as it’s not installed on the client machine.

File Based Win32 App Detection Rules
This Win32 app detection rules verify application presence based on file or folder existence, date, version, or size. You have to provide following details when using this Intune detection rule.
- Path: Enter the full path of the folder that contains the file or folder to detect.
- File or folder: Enter the file or folder to detect.
- Detection method: Select the type of detection method used to validate the presence of the app.
- File or folder exists
- Date modified
- Date created
- String (version)
- Size in MB
A Win32 app detection rules can have multiple File based detection rule. When you have multiple detection rules for app installation, all rules evaluation result must be true for the application to get detected.
Example of File based detection:
Check for file existence:
Check for file version check:
Client side activities:
As explained earlier in this article, you can view client side activities in Intune Extension Manager log. You can see in below logs that client downloaded the latest policy from Microsoft Intune and it’s contains all the details for application including detection rules which we configured in Endpoint Manager portal. The DetectionType 2 represent File / Folder based detection rule.

The Detection rules process starts and it’s checks for the defined rule. As you can see below, we have added two File based detection rules. The first rule was to check file existence while second rule was to check file version. The evaluation of both rules must be true for application to get detected as installed. You can see in IntuneManagementExtension.log that it’s checked for file or folder existence rule first.
[Win32App] Checked filePath: D:\Program Files\WinZip26\Winzip64.exe, Exists: True, applicationDetected: True [Win32App] Checked under Path: D:\Program Files\WinZip26, filePath:D:\Program Files\WinZip26\Winzip64.exe, agent was checking under expanded: D:\Program Files\WinZip26\Winzip64.exe, applicationDetected: True
Later, it’s validated the second detection rule and compared the version installed on client machine with version provided in detection rule. The application will not be offered in this case as both conditions are true and application was detected on computer.
[Win32App] Checked filePath: D:\Program Files\Winzip26\Winzip64.exe, Got versionStr:50.260.14610.0, compareValue 50.260.14610.0 [Win32App] Equal: actualValue: 50.260.14610.0, compareValue: 50.260.14610.0, applicationDetected: True [Win32App] Checked under Path: D:\Program Files\Winzip26, filePath:D:\Program Files\Winzip26\Winzip64.exe, agent was checking under expanded: D:\Program Files\Winzip26\Winzip64.exe, applicationDetected: True
Registry Based Win32 App Detection Rules
This registry based win32 app detection rule verify the application existence based on windows registry key, value existence, string, Integer or version comparison.
- Key path: The full path of the registry key that contains the value to detect.
- Value name: The name of the registry value to detect. If this value is empty, the detection will happen on the key. The (default) value of a key will be used as detection value if the detection method is other than file or folder existence.
- Detection method: Select the type of detection method that’s used to validate the presence of the app. The following detection methods are available in registry based detection rules.
- Key exists
- Key does not exist
- String comparision
- Version comparision
- Integer comparision
Example of Registry based detection:
Please see the Intune registry detection rule example in below screenshot.
Check for string comparison:
Client side activities:
Similar to MSI & File based detection rule, you will see the details of registry detection rule in the policy downloaded at client. The DetectionType 0 represent registry based detection rule

Use custom detection script
The Intune app detection rules support use of PowerShell script to detect Win32 app presence. The following details are required for this app detection method.
- Script file: Select a PowerShell script that will detect the presence of the app on the client. The app will be detected when the script both returns a 0 value exit code and writes a string value to STDOUT.
- Run script as 32-bit process on 64-bit clients: Select Yes to run the script in a 32-bit process on 64-bit clients. Select No (default) to run the script in a 64-bit process on 64-bit clients. 32-bit clients run the script in a 32-bit process.
- Enforce script signature check: Select Yes to verify that a trusted publisher has signed the script, which will allow the script to run with no warnings or prompts displayed. The script will run unblocked. Select No (default) to run the script with user confirmation without signature verification.
The Intune agent checks the results from the script. It reads the values written by the script to the STDOUT stream, the standard error (STDERR) stream, and the exit code. If the script exits with a nonzero value, the script fails and the application detection status is not installed. If the exit code is zero and STDOUT has data, the application detection status is installed.
Exit Code and STDOUT stream
| Exit Code | STDOUT Stream | Detection State |
| 0 | Not Empty | Detected, Application installed |
| 0 | Empty | Not detected, Application not installed |
| Non zero | Empty | Not detected, Application not installed |
| Non zero | Not Empty | Not detected, Application not installed |
Source: https://www.petervanderwoude.nl/post/working-with-custom-detection-rules-for-win32-apps/
Sample detection script:
Here is a sample script to use with Custom detection script rule with Win32 App. The script will check for file existence and it’s version. It will return Exit code 0 and write string value in STDOUT if condition matched. Else, it will return Exit code 0. The Intune extension manager will capture the output written to STDOUT ( using Write-host ) and show that in the log file.
$AppName = "Winzip ver 26.0"
$File = "D:\Program Files\WinZip26\winzip64.exe"
$FileVersion = "50.260.14610 (64-bit)"
Write-Host "Custom script based detection : $AppName"
if (Test-path $File) {
$ActualVersion = (Get-ItemProperty -Path $File).VersionInfo.FileVersion
If ($ActualVersion -eq $FileVersion) {
Write-host "Actual version: $Actualversion, Compared version: $FileVersion"
Write-host "Same version of application installed"
Exit 0}
else {
Write-host "Actual version: $Actualversion, Compared version: $FileVersion"
Write-host "Different Version of application installed"
Exit 0}
}
else {
Write-Host "File $file not found. Application not installed"
Exit 1

Below are the excerpts from Intune extension manager log. The client downloaded the policy which includes everything about win32 app detection rules. The PowerShell script also included in the policy in encrypted form. I removed the lines to make it short. The DetectionType 3 represent custom script based detection rule.
