I posted in the one bug report thread but I've since refined the fix and reduced the attached file.
The attached ZIP file contains:
1. GTK and Pango plain-text configuration files, and the theme configuration for GTK. For whatever reason it doesn't load properly and needs to be provided as a file.
2. Default control2config.txt
3. All images and icons used by RemoteControl2.exe - Great for customizing your RC.
There are no DLLs or EXEs included in the ZIP file anymore as they are unneeded.
Instructions:
1. Create a RC2 folder in your Graal folder or wherever you want.
2. Extract RC2.zip to your RC2 folder.
3. Download and Install RemoteControl2 through Graal if you haven't already.
4. Copy RemoteControl2.exe from your Graal folder into your RC2 folder.
5. Open RemoteControl2.exe
Upon opening it you should have a fully functioning RC2.exe and continue developing under Windows 8.
Credit to the posters on Graalians who figured it out, I just refined it and cleaned it up for distribution.
