Many thanks for your reply Gregory – I will certainly ask my client to check that. Forgive my naivety, but I note that you mention “if it is a SCORM file”. What do you mean by this? I have created the module in Lectora as normal and then used ‘publish to SumTotal’ (having installed the SumTotal extension pack). I select ‘SCORM 1.2 Conformant’ from the Conformance Level dropdown box.
