I can silently install flashfxp , with FlashFXP.exe" /SILENT But then it still needs a serialkey, i can add this manually, but i want to include it with the silent install. Is the serial always stored in the registry? How can i find it? I have the same problem with zonealarm security suite, i actually found the serial in the registry and made a .reg, but it doesnt work? Or is there a switch to add a serialnumber? The /lickey switch for zalarm didnt work for me... I did searches btw. Hope someone can help me
