Important : without the .net 3.5sp1 framework, SliderDock will immediately close.
You can get the framework here:
http://www.microsoft.com/net/Download.aspx
Update : The new setup since v1.15 is now capable to check if .net is installed on your computer, and if it's not found will download it.
Only the zip version needs to have .net installed manually now.
windows 7 comes with .net3.5 pre-installed but you need to go to
"Control Panel -> Programs and Features -> Turn Windows features on or off" to turn it on.
on 64bit OS , don't install in "C:\Program Files(x86)".
