This works (after installation): [HKEY_LOCAL_MACHINE\SOFTWARE\TuneUp\Utilities\7.0] "Company"="XXX" "UserName"="XXX" "LaunchedUpdateWizard"=dword:00000000 "RegCode"="XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" "RegRemindOn"=hex:00,00,00,00,9c,85,18,41 "RemindAgainAfter"=hex:00,00,00,00,9c,85,18,41 "UseCounter"=dword:00000001 But, I discovered that it works only if you install normally (not unattended) and import registry after installation.
