Uninstall .NET Framework 3.0 SP1 in command line

I have been trying to uninstall .NET Framework 3.0 SP1 using command line with the dotnetfx30sp1.exe. I have tried the /remove and /u开发者_StackOverflow中文版ninstall switches but all that happens is it says that it is already installed. Is there anyone that used the command line uninstall command? I'm trying to do a silent uninstall but just trying to uninstall first. Any help would be appreciated.

Thanks

Try this, using msiexec:

msiexec /x {2BA00471-0328-3743-93BD-FA813353A783} /l*v %temp%\netfx30sp1_uninstall_log.txt /qn

Take a look here.
