Unblock media

This patch includes additional security features that may restrict the patch installation process if the installation files have been marked as "blocked" by the operating system.

• We recommend that you copy the installation file(s) to a local drive and unblock them before applying the patch.

• Installing from a shared network drive may result in unpredictable behavior, even if you have followed the procedure to unblock the installation files.

If you intend to use a ZIP or ISO file for installation

Use this procedure to unblock the ZIP or ISO installation file.

1. Copy the ZIP or ISO file of the System Platform installation media to a local drive.

2. Right-click the file.

   1. Select Properties.

   2. If Properties contains an Unblock checkbox, check it.

   3. Select Apply or OK.

3. Extract the ZIP file or mount the ISO file.

4. Run Patch Manager.

5. If the "files blocked" message appears, run the following PowerShell command as an administrator, for example:
   

   Unblock-File -Path "C:\SP2023R2SP1P03.ISO"

   -or-

   Unblock-File -Path "C:\SP2023R2SP1P03.ZIP"

6. Rerun Patch Manager.

If you intend to use extracted installation files

Use this procedure to recursively unblock the installation files that were either extracted from the ZIP file, or copied from a network file share to a local drive.

7. Run the following PowerShell command as an adminstrator:
   

   Get-ChildItem -Path "C:\EXTRACTED_MEDIA" -Recurse | Unblock-File

   where C:\EXTRACTED_MEDIA is the local folder that contains the extracted installation files.

8. Run Patch Manager.
