The below added to my RunOnecEX works.... rem REG ADD %KEY%\080 /VE /D "Nero 7.2.0.3" /f rem REG ADD %KEY%\080 /V 1 /D "%CDDRIVE%\Install\Applications\Nero\Nero.exe /qb /norestart" /f ...However, before Nero installation is complete, 'RunOnceEX' will advance to its next entry. This may cause problems. For this reason, I have Nero as my last install.
