Issue
I have Eclipse IDE for C/C++ Developers on Windows 8.1. I installed Darkest Dark theme from the Marketplace, but it does not work. Upon restart, Eclipse starts with my previous theme and Darkest Dark does not even appear in Preferences window. However, when I open Marketplace again and search for it, it shows as installed. I searched but did not find an answer to this exact problem. Any help?
Solution
Answering my question in case someone else has the same problem. After e-mailing Genuitec support, it turned out the problem was a permissions issue. So I uninstalled Darkest Dark, opened Eclipse as administrator, installed it again and now it works.
