I tried installing Confluence similarly I installed bit bucket and Jira. While installation when I gave my MYSQL DB it started creatting table. It took little more time than expected. Hence I refreshed the page. I get below error.

This gave me a fatal error "Could not load bootstrap from environment" that stops the server from loading. I do not recommend deleting this folder.

[Nic Brough -Adaptavist-]

The folder deleted was half the installation, and Arnand re-installed afterwards.

You should delete the folder if you are trying to do a completely clean re-install.
