I'm trying to upgrade my Smartermail version with the same process that has worked fine when I've done it before following the normal steps. This time while trying to install version 9546  it started off normally asking about the directory and existing installation and then proceeded to install the .NET 10 dependency but then prompted me to exit/cancel the install. If I don't exist it just loops around to the same state. After that initial time it gets to the point of installing dependencies and then prompts to exit without finishing the install. I assume it's having some issues with what is on my system (Windows Server 2016) from a dependency perspective. I can reinstall version 8664 with no issues and that version works fine after install but I'm trying to upgrade to get the new SSL cert functionality that I believe was released in 8747.

Any thoughts on what to look for in the logs to the cause or possible diagnostic methods.

Thanks

Grant
