If you got a compressed archive just use a decompressor
to unpack the contents to the preferred area on your hard
drive.
If you got the application drawer in uncompressed form,
drag it to the preferred area on your hard drive.
In both cases, the application files are self-contained into
a drawers hierarchy. Move the top drawer where preferred and
you're ready to start, no installation of system libraries
or extensions is needed.
To launch the application open the top drawer and double
click on the application icon.
