Updating Third-Party Products
Third-party products are on various DVDs. The PTC Solution Installer requests the DVDs it needs for updating any components you choose to update. For detailed instructions on how to update third-party products refer to their installation documentation. Any additional configurations that are needed to make these products work with Windchill are provided in this guide.
When you are updating an existing Windchill system, update only those third-party products that you are using in your Windchill system.
If you are installing a new Windchill system, use the latest Windchill Third Party Software DVDs shipped with Windchill.

It is very common that third-party products are installed on multiple systems. Be sure to update the products on all systems where they are used.
Some third-party products, such as Cognos (for use with Windchill Business Reporting), require you to uninstall the third-party product before updating your Windchill solution using the PTC Solution Installer. To determine if there is an update to the third-party component, verify the supported version of that component in the Windchill Software Matrices. If the supported version of the third-party product is the same as your current version, you do not need to uninstall your third-party product and may continue to update your Windchill solution.
When updating PTC HTTP Server on an HP-UX system, update PTC HTTP Server before updating the rest of your Windchill solution. Perform the PTC HTTP Server update as a root user and, after the PTC HTTP Server update is complete, manually change the ownership of the PTC HTTP Server files. To do this, execute the following command to change ownership of the PTC HTTP Server directory:
chown -R <user that will update Windchill> apache
