Alfresco is no longer providing an .exe based installer. The installer was never meant for use in any serious capacity apart from evaluation / local development installations, and did not reflect best practices for production use. It just sort of became the "default" way of installing Alfresco for many people who did not know / were not told better.
Since Alfresco 6.0, the default installation / deployment model propagated by Alfresco is based on Docker, and as such, only the Docker images and helm charts are officially provided / supported by Alfresco. They do also provide Docker Compose configuration, but those are explicitly documented as unsupported for production uses. There no longer is any .exe to be found anywhere.
