The requirements for doing a manual installation must be met. Please read the requirements page if you're not sure about the requirements. Proceed only if you have access to a UNIX based environment with Apache, PHP, MySQL or PostgreSQL already installed and running. As mentioned earlier, the database server may run on a different computer than the web server. A manual installation consists of the following steps:

• Setting up a database (MySQL or PostgreSQL)
• Downloading Exponential
• Unpacking Exponential
• Manual configuration of Exponential

The only difference between a normal and a manual installation is the last step. Instead of running the web based setup wizard, Exponential is manually configured by editing a couple of files. The first three steps are explained under the "Installing Exponential on a Linux/UNIX based system" section. The last step is explained under the "Manual configuration of Exponential" section.
