From other post that you was looking for Clarion 10, I think you have problem to upgrade to Clarion 10 with old 3th party template.
And I thing you don´t install the Office Template correctly on the new Clarion 10
Compare the Office template on your old Clarion with the new Clarion 10
(You can compare on the Tools\Edit Template Registry)
Also for sure take APP that only use this template from Old Clarion and Open it on Clarion 10 to be sure the problem from this template or other.
