Hi ! I read the all thread, but couldn't find a solution... he is my problem. I launch the installation from my dvd. But as i also install dreamweaver, it associtaes.js files with it! so when I type start /wait .... winamp.js it opens dream ! when i right click on the .js file, I've got "open with the script command" (not sure of the exact text, it's in french), witch is "c:\windows\system32\cscript.exe" So how do I call from my batch file cscript.exe ? I saw above the wscript command, but I've got this "line 13" error... This is driving me crasy !
