## Installing/Updating Software on Microsoft Windows

### Use

You install or update a component group, installation profile or individual database software components.

The procedure that follows should only be used for updates if you wish to update components for which the software is not stored in the <dependent_path> of the MaxDB installation or if the software installation you want to update is not used by any database instances.

Directories

If you want to update components for which the software is stored in the <dependent_path> of the MaxDB installation and whose database instances use this software installation, you have to update the database instances together with the software (Updating Database Instances and Their Server Software). Otherwise, you risk rendering the database instances incompatible with database software, and you may not be able to start them again.

The system logs the installation process.

### Procedure

...

1. First, unpack the database software to a local directory.
