Are you referring to the CopperDeck2 skins by Pixtudio?
I have not used either the Sysmetrix or Rainlendar programs for a while, so I can't remember whether there is a "Skins" or "Themes" folder in their respective program folders:
Example - "C:\Program Files\Sysmetrix\Skins", or "C:\Program Files\Rainlendar\Skins" folder (or Themes in place of Skins).
Skin folders are placed in either the "Skins" or "Themes" folder if one exists, otherwise you place the skin folder directly in the relevant program folder (just remove the Skins/Themes folder from addresses above).
Basic method:
- Download skin file (it will be a ".zip" file in the specific cases of the CopperDeck2 Sysmetrix and Rainlendar skins).
- Extact the skin folder from the ".zip" file, and then place it in the correct folder using the criteria listed above.
- Start program and apply the skin (skin should now be listed) in the normal fashion.
Note - in some cases, you will need to manually install the font(s) included in the skin folder.
I hope this helps.
