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

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

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

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

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

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

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

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

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

in the user canceling the installation.</note>

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

of your application:</p>

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

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

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

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

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

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

;Supports S60 5th Edition

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

;Supports Symbian^3

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

</codeblock>

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

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