Did you try to check the version in registryYes I did.
I then tried to use the custom update function but as this will be a rather complicated procedure and there is no way to re-edit the package and correct mistakes, I will use Active Directory deployment with a PowerShell script to deploy this full version.
DCourtel: I don't think that this is an official version from Adobe. I guess this is a malware transport package from some download sites without a good reputation.
