Installing the official Nxt Software on Windows

Very important: Before you begin, you must have the latest version of Java on your computer in order to run Nxt. If you do not, everything will seem fine until you get an ugly error about an "unsupported major/minor version", which will cause you to get upset and post unnecessarily on the support forums, and we don't want that! Get Java at http://www.java.com/../en/

Downloads

Installation instructions

  1. Download the .zip of the official client from https://bitbucket.org/../JeanLucPicard/nxt/downloads/nxt-client-1.3.4.zip
  2. Extract files in a nxt folder. You can create this folder anywhere; many people put it on the root of their C:\ drive.

  3. Locate the file called run.bat in the nxt folder, and run it by double-clicking on it. If all goes well, you should see something like this:

    As long as this server window is open, you're running a Nxt node.
  4. Open http://localhost:7876/ to access the web-based client for Nxt.

    • NOTE: Avoid just X'ing out the server window if you want to close down the software. To prevent data corruption, you should stop the process properly. You can do this in Windows by selecting the server window and pressing Ctrl+C
    • NOTE: Some browsers have problems using "localhost". If you get an error, try http://127.0.0.1:7876/. "localhost" and "127.0.0.1" mean the same thing.
  5. If you already have created a Nxt account, click in 'Returning User' to introduce your password. If you need to create your Nxt account, click here for instructions to Create a New Nxt Account.

Troubleshooting

If in step 3, the window suddenly closes, an error has occurred. Edit run.bat and insert the word "pause" in a new line at the bottom of the file. This will cause the window to wait for a keypress before closing, so that you can see any error messages.

General Tips

Security Tips

  • When creating a Nxt account, if you design your own passphrase, ONLY USE a high security passphrase (35+ characters, truly random). Your Nxt WILL eventually be stolen if you don't! Here's how to choose a strong password.
  • Unless you really know what you are doing, do 'not' run Nxt on a virtual server (VPS). Even if you connect to your VPS securely via SSH, you are still not safe because all VPSs have backdoors.
  • Nxt's peer-to-peer communications port is 7874 (tcp). This port is the only port that needs to be open to run Nxt.
  • Nxt also uses port 7876 for its web client interface. You should close port 7876 on your firewall to prevent other people from accessing your server.
