# Installation Registry

The Universal Installer maintains an installation registry. The registry location depends on the platform.

This section explains where the registry files are located. The file names include the prefix vpd, which stands for Vital Product Database.

Warning: Do not edit, modify, rename, move, or remove any of the registry vpd files.

## UNIX Platforms

If installation is performed by a regular user (non-root), the installation registry is maintained in the following files in the user's home directory:

    $HOME/INSTALLSHIELD

If installation is performed by super-user (root), the installation registry is maintained as follows:

- On Solaris and HP-UX, in the root user's home directory (which is /) as `vpd` files.
- On AIX, in the /usr/lib/objrepos directory as `vpd` files.
