Custom made button in excel 2010 not visible in excel 2007

[freggel]

I've created in excel 2010 an add-in which creates new buttons to the ribbon.
All works fine in excel 2010.
When using this add-in on my collaegues computer, the add-in and the macro's work fine, but buttons aren't visible.
So I think the problem is caused in xlm.
Ribbon was created using the Custom UI Editor (installed on my pc since excel 2007)

partof the code
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon>
<tabs>
<tab id="customTab" label="VS LOT 2" >
...
</tabs>
</ribbon>
</customUI>

anybody any suggestions?
thnx
Bart

Dear All,

found the solution: 2 important things to notice:
First of all, excel 2010 CAN use other scheme than 2007

Excel 2010
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui">

Excel 2007
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
​

On the second hand, it's important to notice that when using the Custom User Editor for Microsoft Office you can right-click on the 'book1.xlsm' which allows you to select the scheme (2007 or 2010).

==> if you're not using the new stuff of Excel 2010, just choose excel 2007 scheme
