Assalamualaikum wr.wb
mau tanya masalah custom ribbon.kode berikut bisa jalan di customui 2006

<customUI onLoad="LoadRibbonUI" xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<commands>
<command idMso="ApplicationOptionsDialog" enabled="false"/>
<command idMso="FileExit" enabled="false"/>
</commands>
<ribbon>

<officeMenu>
<button idMso="FileNew" visible="false"/>
<button idMso="FileOpen" visible="false"/>
<button idMso="FileSave" visible="false"/>
<splitButton idMso="FileSaveAsMenu" visible="false"></splitButton>
<splitButton idMso="FilePrintMenu" visible="false"></splitButton>
<menu idMso="FilePrepareMenu" visible="false"></menu>
<menu idMso="FileSendMenu" visible="false"></menu>
<menu idMso="MenuPublish" visible="false"></menu>
<button idMso="FileClose" visible="false"/>

</officeMenu>
</ribbon >
</customUI >

tapi ketika mau digunakan di 2010 tidak work / jalan padahal ini

office/2006/01/customui"
