I'm just trying to figure out how everything is working before I start with a major installation process during setup. what I did is created just one cmd to install skype silently however when windows is starting up I get the error message that it can't find the setupskype.exe file. In order to do this I created a INSTALL folder on my c drive, en I also did this in the windows unattended setup files where I copied the setup.exe file into but this doesn't do the trick either :-( then I tried to execute this cmd and I get this error message mentioned above can someone tell me what I'm doing wrong? this is the code cmdow @ /HID @Echo Off SET PP=%SystemDrive%\Install\ SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx REG ADD %KEY% /V TITLE /D "Installeren van Programma's" /f REG ADD %KEY%\000 /VE /D "skype 1.4" /f REG ADD %KEY%\000 /V 1 /D "%PP%SkypeSetup.exe /VERYSILENT /SP-" /f EXIT thanks for your help Paul
