As TG pointed out, theme manager applies the various skins within the Suite file. Each skin contained within the suite, will need to have the corresponding program installed. If the suite contains Windowblinds,DX widgets,Iconpackage,Cursors. etc you will need each program installed to utilize the skin for each. If you do not have some of the programs installed for example:CursorFX, it will simply skip trying to apply the CurFX skin, and proceed with the rest.
