I did this..."Download file "NYC Core Wallet v0.10.4.zip" and don't understand what to do after that. It's pretty confusing to a non tech type person.
NYC would be great if they had a simple wallet that didn't need a computer programmer, lol.
Type into youtube "almost heros learning to read" and that's me when I get to this part of the instructions, "Extract Blockchain and Chainstate zip files into your NYC file folder where your NYC .conf file is located and allow to overwrite."
Extract NYC Core Wallet v0.10.4.exe you just downloaded, run and close the app. Download the other file: NYC Core Wallet Blockchain and Chainstate Dec 17, 2017. When it´s done, extract all files to C:\Users\YourUsername\AppData\Roaming\Newyorkcoin overwriting the original files. Run NYC Core Wallet v0.10.4.exe again and let it sync.
