We upgraded about 8 different client SmarterMail servers, most of which were running SSL certs, from various builds of 14.X, most of which without seeing any issuesm with either the licensing or certificate installation.
When you did your upgrade, did you STOP both the SmarterMail SERVICE and the SmarterMail WEBSITE in IIS?
If not, then you may have had some issues with locked files during your upgrade.
If your ERROR and ADMINISTRATOR logs are set to detailed, within SmarterMail, tbey may provide additional information about the issues you experienced
If you continue to see errors, then iI would consider uninstall the latest version, rebooting the server on which your SmarterMail program is installed, and reinstalling.
If you did not use the default path for your original SmarterMail installation , then please make certain to enter the correct path information diring the reinstall phase
You may also have to reenter your licensing information again, so pay attention to Smartermail's "down time" they have scheduled for this weekend so it doesn't interfere with your efforts.
Please keep us posted as to your results and outcome. .
