Yeah not working.
I had it working on 17.12 mingw version (the latest) on my C drive, but when i reinstalled to an external drive (D:), the config file wasn't in the 'C:\Users\[USER]\AppData\Roaming\CodeBlocks'-folder, but in the 'D:\Program Files (x86)\CodeBlocks'-folder.
After following the guide, and using cb_share_config on the default.conf on the D: drive location; doing 'settings>>editor>>Syntax Highlighting' on the bottom window, the colors do change.
But the main editor doesn't change, not even with a reboot.
I tried making a new project, without success on running the theme...
*Windows 10 Home 64bit, 16GB RAM, N5000 CPU, 32GB of free SSD space left on C, and a few terabytes on D.
Edit: seems like I also don't get a blank window to code in. Something appears broken.
I'll reinstall.
