hehe you was faster then me , thats the way. But it is not necessarily to lock the archiv. Then you use REG ADD %KEY%\050 /VE /D "Winrar 3.40 FINAL" /f REG ADD %KEY%\050 /V 1 /D "%systemdrive%\install\WinRar\Winrar3.40.exe /s /W" /f to install silent For lazy people use the file attachted and just add the files from winrar folder Rename the fille to .exe
