looks like an error/issue with the actual v16.3.6726 installation package!
SmarterMail cannot be installed on our production mailserver running Windows 2012R2,
hope this will be fixed ASAP - meanwhile we are forced to reinstall v16.3.6705
We are licensed Enterprise customer... so not a special Home/Free-user-issue!
