<p>Packages that are preinstalled using InterpretSIS must follow certain rules

</fig> <p>* The base SA and associated upgrades are removed ** The base SA
is removed prior to the installation of the SA upgrade. </p> <p>InterpretSIS
returns an error if the rules are violated during an upgrade. It supports
variants of file names and usage of wildcards for Stub SIS files. </p> </section>
<section id="GUID-293CEBCE-78B3-4D3A-90F4-281AD905FE14"><title>Non-removable
package upgrade rules</title> <p>The following table summarizes the rules
that apply when performing patch upgrade, partial upgrade or replacement of <i>non-removable</i> packages
installed using <codeph>InterpretSIS</codeph> with the <codeph>NR</codeph> option
set (<codeph>+nonremovablepkg</codeph>). The general rule is that a removable
package cannot be made non-removable, and a non-removable package cannot be
made removable.</p> <fig id="GUID-20A6F1E5-45DC-5AC0-92F2-181A5AFB77F0">

</fig> <p>** The original <codeph>PA</codeph> is removed, including the private
directory, before upgrading. </p><p><b>Notes:</b></p><ul>
<li><p>If the base package (SA) is removable then patch upgrade (SP) must
also be removable.</p></li>
<li><p>If base package (SA) is removable but partial upgrade (PU ) is non-removable
then both base package and partial upgrades (SA+PU) are non-removable.</p></li>
<li><p><codeph>NR</codeph> upgrades are performed to the same drive as the
original package. </p></li>
<li><p><codeph>NR </codeph>upgrades or patches delivered on preinstalled media
cards are rejected as invalid. Any invalid upgrade generates a <codeph>KErrInvalidUpgrade</codeph> error. </p></li>
<li><p>Back-up and restore is not functional for preinstalled SIS files that
are in the system drive. </p></li>
<li><p>Preinstalled SIS files that are in the system drive can be uninstalled
if <codeph>DeletePreinstalledFilesOnUninstall</codeph> is set in <filepath>swipolicy.ini</filepath> file.
