Update from Cubase 8 Pro 8.0.10 to 8.0.20 fails

Update from Cubase 8 Pro 8.0.10 to 8.0.20 fails

I have downloaded the update a few times but each time I try to upgrade the installer tells me that Cubase 8 Pro is not installed and therefore NO CHANGES. It is installed, fully licenced etc. Not sure what I am doing wrong. This is the first issue I have had with Cubase.

I have updated the eLicensor, re activated etc. but still no joy.

Any help would be gratefully acknowledged.

Thanks,

Mal :confused:
