    12 <concept id="GUID-CFC21A23-0299-4420-BB60-584D10C8913A" xml:lang="en"><title>Updating

    13 the platform UID</title><shortdesc>This topic describes how to update the platform UID.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

    14 <p>When porting applications from S60 5th Edition to Symbian^3, you can include

    15 the Symbian^3 platform UID in your application's <codeph>.pkg</codeph> file

    16 and create a new <codeph>.sis</codeph> installation package using the modified <codeph>.pkg</codeph> file.

    17 The platform UID for Symbian^3 is <codeph>0x20022E6D</codeph>.</p>

    18 <note> If you do not include the Symbian^3 platform UID in your package file

    19 and create a new <codeph>.sis</codeph> installation package, the user gets

    20 a compatibility warning when installing the application. The warning may result

    21 in the user canceling the installation.</note>

    22 <p>To add Symbian^3 UID, include the following line in the <codeph>.pkg</codeph> file

    23 of your application:</p>

    24 <codeblock xml:space="preserve">[0x20022E6D], 0, 0, 0, {"Series60ProductID"}</codeblock>

    25 <p>If you have verified that the same binary can be used on multiple Symbian

    26 platform releases, you can include platform UIDs for multiple Symbian platform

    27 releases in your package file as illustrated by the following example:</p>

    28 <codeblock xml:space="preserve">;Supports S60 3.0

    29 [0x101F7961], 0, 0, 0, {"Series60ProductID"}

    30 

    31 ;Supports S60 5th Edition

    32 [0x1028315F], 0, 0, 0, {"Series60ProductID"}

    33 

    34 ;Supports Symbian^3

    35 [0x20022E6D], 0, 0, 0, {"Series60ProductID"}

    36 </codeblock>

    37 <p>For more information and a list of the platform UIDs used in earlier Symbian

    38 platform releases, see <xref href="GUID-FBA816FE-E188-4A40-9B9B-D47F7D3390AE.dita">Platform
