Can you explain that in more detail?, i downloaded the redistributable but still nothing, maybe some instructions?
Assuming you've already installed wine, here is what you do
1. Download
winetricks2. Move the winetricks file from your downloads into your home folder (The folder above Documents, etc)
3. Open a terminal and type
bash winetricks vcrun20154. Wait for an installer gui to pop up, it may take a minute
5. Follow the prompts on the gui to finish installing Visual C++ Redistributable
6. Run the windows version of Blockland through wine following the other instructions in this thread
No guarantees that this works, I don't use OSX so it's not like I've tested it there or anything. Just an educated guess.
