If you have problems installing any of the products in the Rational® DOORS® product family, try these solutions before you contact Rational Support for help.
Stop and shut down all applications before you install the software.
Turn off virus protection software.
When virus protection software is running in the background, it can interfere with the installation of any software product because of the way installers extract files when they install them on the computer.
Make sure that the system meets the system requirements for the product you are trying to
install. Details of system requirements are on the IBM® System Requirements
website.
Restart your computer, and then try installing Rational DOORS again.
