batch file

[lspook2]

i'm trying to automate the install of nod32 antivirus. i have automated that part via a batch file to install it siletly. what i am trying to do now is put all this on cd and when they run the batch file it will search for a cd drive. i cant set it to d:\ because not all computers have the cd rom on d. the install will be done through windows.
i tried set patch %cdrom%:\.... but doesnt change over the drive letter to the cd.

lspook2,
If you going to put it all on a cd then why not create an
autorun.ini file
example:

[autorun]
open=nod32.exe
