Hello! I have just integrated the driver for Audigy2 in winnt, no problem. The driver is installed. I want then integrated the Mediasource software. I installed with the parameter - R, I copied the setup.iss in the same folder. In RunOnceEx, I put: REG ADD %KEY%\016 /VE /D "Mediasource 2" /f REG ADD %KEY%\016 /V 1 /D "%systemdrive%\Creative\Cms\Setup\Setup.exe - S - f1"%systemdrive%\Creative\Cms\Setup\setup.iss"" /f But nothing to make, in the ".log", I have in answer: ResultCode=-105. I tried with - f1 without the quotation marks, then idem with /f1. And, I tested with Just setup.exe /S or - S. But still not of installation. PS: Sorry for my english, but i'm french.
