License Key Error: no office addon

Have following error on loading a native office doc in webviewer “License Key Error: no office addon”, documentType is set to ‘office’.

Is this actually what is says on the tin, that the I need a new license key which will allow native office files to be viewer, or am I missing files, or is it another problem.

Was a demo license and also used our work license, both gave this error. Does load PDF no problem (documentType is set to ‘pdf’)

Thanks for any help

Could you please forward your license information to so that we can take a look at your account on our end?

Thank you.
