If you have Litestep itself installed...double clicking on the 'themename.lsz' will install the theme.

If you just wish to look at what is in the lsz....rename it to a zip....all it is is a renamed archive file.

As a zip you can use your fave Winzip or whatever to look at it...

It shouldn't be an 'lsz.doc'.....the file suffix is 'lsz' as in 'theme.lsz'.....change that to 'theme.zip' to open with winzip.

To actually USE a 'theme.lsz' you must have Litestep.exe installed on your computer.....it is a 'Shell' program which replaces your normal Windows shell which is actually called 'explorer.exe'...
