I found the windows installer in .exe for version 18.104.22.168. I would like to know if there is a more recent version in the form of an .exe if he would like? and where it is because it is not really easy to find these files.
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.
