How do I get this to silently install? I'm 100% it uses NSIS and I followed that guide. It opened up the install but didn't do it silently and I had to set the options for it. So far I got: ECHO. ECHO Registering CloneCD... REGEDIT /S %systemdrive%\install\Applications\CloneCD\register.reg ECHO. ECHO Installing CloneCD 4.2.0.2 ECHO Please wait... start /wait %systemdrive%\install\Applications\CloneCD\CloneCD.exe /s The registering part works (doesn't give me any errors, haven't checked if it's regged yet since CloneCD won't install). With what I have given above, it just opens up the install and the "/s", which was suggested in the guide, didn't do anything. I followed this: http://unattended.msfn.org/xp/applications/nsis.htm Any help is greatly appreciated. Thanks . By the way, if it matters, I'm doing an SP1a unattended CD, not SP2.
