@Stephane8,
Seems download and install of the VMware Skyline Health Diagnostics using the ISO install media file has been deprecated starting from version 4.0 onwards.
Well, I see we have OVA as well as an Patch bundle available for 4.0.1-22433617 to download from customer connect portal which could be used to perform upgrade for offline environment.
If you think your queries have been answered, Mark this response as "Correct" or "Helpful" and consider giving kudos to appreciate!
Regards,
Shen
