<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>
