Hey guys, does anyone know how to change the CD-ROM drive letter before my applications will install from the CD? I'm using the following code in my "RunOnceEx.cmd" to install all my stuff from the CD/DVD: FOR %%i IN (D E F G H I J K L M N O P Q R S T U V W X Y Z) DO IF EXIST %%i:\CD.txt SET CDROM=%%i: The problem is, that the setup is always using the letter D: for the CD-ROM drive but I'd like to assign this letter to my DATA-Partition.
