## Symptoms

- * This message appears when the Jumbo Hotfix installation finishes: "*The updated inspect files were NOT installed due to signature mismatches or error"*.

* Policy installation fails with one or both of these messages:

  * "`ERROR: cannot find <iked_ports_block_in> anywhere`"

  * "`ERROR: cannot find <iked_ports_block_out> anywhere`"

## Cause

During Jumbo Hotfix installation, the installer checks whether the Inspect files were manually changed.

If the Jumbo Hotfix includes updated *\*.def* files and the installer detects manual changes in the existing Inspect files, it does not replace those files automatically. This prevents the installer from overwriting local changes without administrator review.
