By using a script to deploy the Patch My PC (PMPC) certificate, you can either deploy the certificate as a:
In environments where a company configures an all-signed PowerShell policy or enforces script signature checking on the Win32 app in the Intune admin center, all scripts must be signed by a trusted publisher. Our script helps import the required certificate into the Trusted Publisher store to ensure that scripts signed by PMPC can be executed without issues.
To deploy our code signing certificate using a script, first download our scripts from:

**Note**
You can find out more details about these scripts and what they do by reviewing the ReadMe.md file included with the scripts.
Certificates to Deploy
There are two distinct use cases in PMPC Cloud that require separate certificates:
- Intune Detection and Requirement Scripts
Used to sign Intune detection and requirement scripts for Win32 applications published through PMPC Cloud. - Patch My PC Helper Scripts
Used to sign required and recommended pre/post “helper” scripts for certain applications in the PMPC catalog. These helper scripts perform essential tasks such as stopping processes, uninstalling older software versions, or configuring application behavior during deployment to ensure successful app installation.
1. Deploy the Certificate use to sign Intune Detection and Requirement Scripts
To deploy our certificate using a script, follow Create a script policy and assign it using the following values.

The following log snippet shows the HealthScripts.log entry if the pre-remediation (detection) script found the certificate already installed in the local computer’s Trusted Publishers store.
The following log snippet shows the HealthScripts.log entry if the pre-remediation (detection) script did not find the certificate already installed in the local machine’s Trusted Publishers store (the Exit code of the script is 1).
The following log snippet shows the HealthScripts.log entry if the pre-remediation (detection) script did not find the certificate already installed in the local machine’s Trusted Publishers store and the remediation script was run successfully (Exit code of the script is 0).
