Office Template component  error

Office Template component  error

i tried installing extension in  integration studio and i get this error "Unable to find the class 'OutSystems.NssOfficeTemplate.CssOfficeTemplate' in the file 'OutSystems.NssOfficeTemplate.dll'."
Hello Tmlewin,

Did you changed anything in the integration studio?

Did you installed on the server the Open XML SDK 2.0 for Microsoft Office requirement?

You can find it here:

Is the your installed version the latest available here?

Hope it helps you.
Kind regards.

Daniel Martins.
