Use the System plugin to invoke the Windows API function GetDriveType. I'll post back here with the exact NSIS command if I can work it out for you.

[edit]Fortunately system.nsh (in contrib\system) already defines sysGetDriveType. This script should help you:-

OutFile "blah.exe"

!include "${NSISDIR}\Contrib\System\System.nsh"

Section -
  StrCpy $1 "c:\"
  System::Call '${sysGetDriveType}(r1) .r0'
  DetailPrint "Boo: $1 $0"
  IntCmp $0 5 0 notcddrive
    MessageBox MB_OK "Drive $1 is a cd drive"
  notcddrive:
SectionEnd

FYI 5 is the drive type code of a cd drive as far as I can tell, well it works on my system anyway[/edit]

ok
Thank you for your help!
It seems to work fine, but i don't remember and i don't arrive to find how to catch the "c:\" when you have a full path like "c:\progam files\my app". I know that there is a function (or a pluggin) to do it, but I can't find it!!!
Perhaps somebody can help me???

you could just use strcpy $0 "C:\program files\my app" 3 which will grab the first three characters
