Product: Symantec Protection Engine -- Error 1722.There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action UpdateAppName, location: C:\Program Files\Symantec\Scan Engine\, command: C:\Program Files\Symantec\Scan Engine\\XMLModifier.exe -s "/configuration/Miscellaneous/AppName/@value" "Custom Application Name" configuration.xml

Decided to perform the install without doing the custom changes prior to kicking it off. Just went with a change to ports and other defaults. The installation succeeded.
After the successful installation the command that was blowing up the install was run from a command prompt which was pointing to "C:\Program Files\Symantec\Scan Engine\"
XMLModifier.exe -s "/configuration/Miscellaneous/AppName/@value" "Custom Application Name" configuration.xml
