"Your system has not been modified. To complete installation at another time, please run setup again.
Fatal error during installation. Click Finish to exit the setup."

You may receive this error when trying to install WordPerfect Office X5. It is caused by a conflict between the WordPerfect iFilter and another software application already installed on your computer.

To get around this, you will need to install WordPerfect Office X5 in Safe Mode. The following steps will guide you through this process.

Download the file "Safe Mode Install" from the following link:]

Extract the file within the zip, "Safe Mode Install Services.reg".
Double click on this registry file and click to allow it to be merged into your Windows Registry.

Next you will need to restart the computer into Safe Mode with Networking.
To do this:

Restart your computer and start tapping on the F8 key before Windows begins to load.

This should open the Advanced Boot Options menu. (If not, restart the computer and try again.)

Use the arrow keys on the keyboard to select "Safe Mode with Networking" and press Enter.

Once the system is booted fully into Safe Mode, try installing WordPerfect Office X5 again.

Once the installation is complete, restart your computer.
This will return your computer to normal Windows functionality.
