I have been trying to install the IDS in silent mode but the problem is that whenever I type the comand :- "setup.exe -s C:\TEMP\silent.ini -l C:\TEMP\silent.log" from the server product folder path nothing happens.
For your kind information I have already made the necessary changes in the silent.ini and copied it in the temp folder. When I only type the command :- "setup" or "setup.exe -l C:\TEMP\silent.log" it runs quite fine. Can any one tell me what might be the problem.

And thanks for everyone who read this post.
