Download the updated version of miner from : 
https://github.com/btscube/steem/releases/

Reference - https://steemit.com/steem/@bitcube/steem-windows-wallet-and-miner-v0-12-0

Download the blockchain from:
http://www.steemitup.eu/

Copy the downloaded blockchain folder 'witness_node_data_dir' inside the miner folder 'steem-win-x64-012'.

Modify the config.ini as per your account and machine:

<code># name of witness controlled by this node (e.g. initwitness )
witness = "your-steem-account-name"</code>

<code># name of miner and its private key (e.g. ["account","WIF PRIVATE KEY"] )
miner = ["your-steem-account-name","5YourPrivateWIFKeyIsVeryLong"]</code>

Private key: Permissions -> Active/Owner

<code># Number of threads to use for proof of work mining
mining-threads = 2</code>

You can decide mining threads as per your CPU usage and the number of processor cores. 

<code># Endpoint for websocket RPC to listen on
rpc-endpoint = 127.0.0.1:8090</code>

Run steemd.exe and begin mining! :)

Please note that actual mining may take few hours to start.
