## Before You Start

Before applying this update, please make sure that your environment meets the following requirements:

For sites running:

- *Uniprint 9.0 R2* - if you are running a version of Pharos Print Center earlier than 3.4.2: you will need to either:
  - upgrade to the latest SP4 or SP5 version (PPC 3.4.3 or 3.6.0 or later) before applying the updated certificate
  - or ensure that the following file is the latest version:
    - C:\inetpub\wwwroot\PharosAPI\bin\implementations\MobileDevicePushNotifications\*Push.Sharp.Apple.dll*
    - If the version is dated earlier than 10/19/2016, please contact Pharos Support for an updated file.

- *Uniprint 9.0*: If you are running Pharos Print Center earlier than 1.7.17, please upgrade your Print Center to version 1.7.17 before updating the certificate file per the instructions below.

## Installation

The update affects Push Notifications to iOS Mobile Devices from the Pharos Print Center and should be applied to **all** machines running the **Pharos API Print Center Services**.

### To apply the update:

1. Ensure your environment is running the correct version as described above.
2. Open the Pharos API folder (typically in **ProgramData\PharosSystems\Pharos API**).
3. Rename the existing file to **MobileDevicePushNotifications.old**. (Simply append .old to the end of the existing file name.)
4. Copy the new supplied version of **MobileDevicePushNotifications.p12** file into the **ProgramData\PharosSystems\Pharos API** folder.
5. In IIS Manager, restart the Pharos [ASP.NET](http://ASP.NET) V4.0 Application Pool.

Applying this update constitutes acceptance of the conditions specified in your license agreement. To view the license agreement, please refer to the *license.rtf* file on your Pharos CD.

## Details

*This update addresses the following issue:*

Notifications on iOS devices require a certificate to authenticate with Apple's notification service. This certificate is installed along with the Print Center. The current certificate will expire on Nov 22 2020. If expired then Pharos Print App will no longer receive notifications. This is a mandatory update for Pharos Print App users and it includes an updated certificate.
