# Patch Installation Failure - "Error 1612"

## Problem

Patch installation fails with a fatal error. The root cause of this is error 1612, which occurs because the feature you are trying to use is not available on the network resource or the installation source of the product is unavailable.

## Cause

Typically, when an MSI-based product is uninstalled, repaired, or upgraded, the previous installer (.msi file) must be available to complete the operation. During installation, the Windows Installer usually copies the MSI file to `C:\Windows\Installer`.

When you uninstall a product, Windows Installer will first try to perform the uninstall using the MSI file saved in `C:\Windows\Installer`. If the MSI file does not exist in `C:\Windows\Installer`, it will attempt to uninstall using the original path used to perform the installation. If the MSI file does not exist in either `C:\Windows\Installer` or the original source folder, you will receive this error.

## Resolution

1. If only a few systems are affected by this error, you may manually run the troubleshooter pack suggested by Microsoft to uninstall the products.  
   [Microsoft's fix for uninstalling products](https://support.microsoft.com/en-us/topic/fix-problems-that-block-programs-from-being-installed-or-removed-cca7d1b6-65a9-3d98-426b-e9f927e1eb4d)

2. If not, you can resolve this by using the old installer file and placing it in the same location before installing the new version. This can be done using the Software Deployment option in Endpoint Central by following the steps below:

   - Create the latest package of the software (for example: Google Chrome) from its template available under Software Deployment.
   - Modify the package and in **Pre-Deployment Activities**, choose the **File Folder Operation** option and upload the file. (The file name and file path should be the same as seen in the error screenshot you receive.)

   - Then in **Post-Deployment Activities**, choose **File Folder Operation**, and select the delete option to remove the file from the location it was copied to after installation of the new version.
