This works for me:
1. Step - Silent Setup
\setup\setup.exe /qb-! ALLUSERS=1 SERIALNUMBER=xxxxxxx-xxxxxxx-xxxxxxx-xxxxxxx
2. Step - No Eula Window for all Users
[HKEY_LOCAL_MACHINE\SOFTWARE\Corel\CorelDRAW\15.0]
"ShowEULA"=dword:00000000
3. Step - No Welcom Screen
[HKEY_CURRENT_USER\Software\Corel\CorelDRAW\15.0\Draw\Application Preferences\Startup]
"InitialAction"="6"
4. Step - Never Register - Stop and disable Corel Register Service with Batch and set Register Reminder to "Never Remind"
Batch:
sc stop psi_svc_2
sc config psi_svc_2 start= disabled
Registry:
[HKEY_CURRENT_USER\Software\Corel\CorelDRAW\15.0\DR15]
"Schedule"=hex:10,00,00,00,01,00,02,00,ff,ff,ff,ff,ff,ff,01,00
