To install Historian, Historian Client, Application Server, or InTouch, you can choose not to install or copy unnecessary files.

The root directory contains the installation program (Setup.exe) and several document files. One file in the root directory is absolutely required: Setup.exe (about 2,200 KB). The remaining files are documents: Getting Started with AVEVA Licensing, the System Platform Installation Guide, the System Platform Virtual Implementation Guide, the System Platform Getting Started Guide, and the System Platform Readme.
The entire InstallITK folder (about 9 MB) is required.

The following table shows which subfolders in the InstallFiles folder are required for Historian, Historian Client, Application Server (including AVEVA OMI run time), and InTouch HMI development and run time. You can delete folders that are not required for the product you are installing. All file and folder sizes are approximate and provided for reference only.
