ok when i click download something pops up that says open or save and i click open

Well after when you click open browse to the location where you installed litestep.
ex:
C:\Litestep
then look for a folder named Utilities
Select the LSThemeInstaller.exe
Then select open
LSthemeInstaller will ask you to download modules the theme needs
Select download...
YOU NEED INTERNET ACCESS TO INSTALL THEMES!

Now everytime you download a theme it will self install
if you have lsthemeinstaller selected to the file instead of winrar!

There are a couple dialog boxes that may open also
--------------------
Themevars.rc
and
Do you want to revert to default litestep theme?
--------------------

These settings are controlled by the lsthemeinstaller.exe
goto your popup menu
select Litestep
goto Utilities
Select lsthemeinstaller.exe
once opened select Settings

In this dialog box you can shut off and enable certain options...!

My tip for the week!
Enjoy!
