I don't understand what you mean by "map"...
In any case, proceed as follow:
- uninstall all viewers.
- download the official viewer (the v1.19.0.5 one, since you want to use the legacy branch of the Cool SL Viewer). The link is given on
the website (it's the "get it from LL" link, along the corresponding Cool SL Viewer version).
- install the official viewer v1.19.0.5.
- install the Cool SL Viewer v1.19.0.5
in the same directory as the official viewer v1.19.0.5.
See the Installation howtos in this forum for more details.
