Three short guides, two of them with pictures of the real app, and one address to write to.

Someone is helping me

  1. Step 1
    Windows' blue 'Windows protected your PC' dialog after More info: App NelkiraSetup-0.6.0.exe, Publisher Unknown publisher, Run anyway and Don't run.
    Real Nelkira 0.6.0 (test build of the release source), Windows SmartScreen on the test PC, 31 October 2026.

    If Windows says ‘Windows protected your PC’

    Choose More info, then Run anyway.

    Nelkira is not code-signed yet, so Windows asks before it runs. You can check the file against its SHA-256 on the download page.

  2. Step 2
    Setup's one question: Will people connect when nobody is at this PC? with No, only while someone is here selected, and Install.
    Real Nelkira 0.6.0 (test build of the release source), Setup, 31 October 2026.

    Setup asks one question

    Setup asks ‘Will people connect when nobody is at this PC?’ Choose No unless your IT team told you Yes.

    Yes needs an administrator and changes what a helper can do; the security page says what.

  3. Step 3
    The Nelkira window the first time it opens: Your number 862 471 650, a password with a Copy button, and Waiting for a connection.
    Real Nelkira 0.6.0 (test build of the release source), the main window, first open, 31 October 2026.

    Read out the number and password

    Nelkira shows your number and a password. Read both to the person helping you.

    Windows may ask whether Nelkira can use the network. Either answer works; if you choose Cancel, sessions go through the relay even on your own network.

When your helper connects: the prompt, Allow, then the amber Screen shared sign. Real time, 10 seconds.Real Nelkira 0.6.0 (test build of the release source), the far PC's screen, 31 October 2026.

To end the session

Press the × on the amber ‘Screen shared’ sign at the bottom right of your screen. Closing the Nelkira window does not end it: Nelkira stays on, so your helper can still reach this PC. Someone with the password or a remembered device can connect again; Stop sharing, in the Nelkira window or in the Nelkira menu by the clock, ends every session and keeps everyone out until you press Start sharing.

I’m helping someone

  1. Step 1
    The number and password panel of Nelkira on the PC being reached: Your number 862 471 650 and a one-time password.
    The PC shows its number and a password; the person there reads them to you.Real Nelkira 0.6.0 (test build of the release source), the main window, 31 October 2026.

    Ask for the number

    The PC you reach shows a nine-digit number and a password. Ask the person there to read them to you; the number stays with the PC, the password changes each time Nelkira starts there unless a fixed one was set.

  2. Step 2
    Connect to another machine: the number 862 471 650 typed in, the password left blank, and the Connect button.
    The helper types the PC's number. With no password, the person there is asked.Real Nelkira 0.6.0 (test build of the release source), the main window, 31 October 2026.

    Type it, then wait for Allow or type the password

    In Nelkira on your PC, or in Nelkira Go on your phone. Leave the password blank and the person at the PC is asked to allow you; type the password they read you and you go straight in. Tick Remember as you do and your device can come back without it.

  3. Step 3
    The Nelkira session window: the far PC's desktop filling it, with a Notepad file open and the session bar across the top.
    Working on their screen, in a window on yours. The black box is where their Screen shared sign sits; it is not sent.Real Nelkira 0.6.0 (test build of the release source), the session window, 31 October 2026.

    The session bar

    View only, Privacy screen, the PC’s other screens, picture quality, full screen, + for another PC in its own tab, and End. Ctrl+Alt+Del works on PCs set up for access when nobody is there.

    Said plainly: Privacy screen blocks their keyboard and mouse only with administrator rights, or on a PC set up for access when nobody is there. Using it to hide from the PC’s own user breaches the Acceptable Use Policy.

A real session, start to finish, in real time (43 seconds): the helper on the left, the far PC on the right. The test driver paused between steps; a person is quicker. The number and password in the helper's own panel are placeholders of the screenshot tool.Real Nelkira 0.6.0 (test build of the release source), the main and session windows, and the far PC's screen, 1 November 2026.

It won’t connect

  1. Run the connection test on both PCs. It measures the line to the relay in Mumbai, India, in under half a minute, and says which picture mode the line can carry.
  2. Check that Nelkira is running on the PC you want to reach and shows its number. A PC installed for use while someone is here can be reached only while someone is signed in to Windows there; from release 0.5.0 an administrator can set a PC up for access when nobody is there.
  3. The relay is reached on port 443, the port web browsing uses. If a browser on that PC can open nelkira.com, the relay is reachable, and nothing needs to be opened on the router.
  4. On the same network, a direct path needs Windows Firewall to allow Nelkira; where it refuses, the relay carries the session anyway, since both are tried at the same time.
  5. Wrong password? Ask for it again: it changes each time Nelkira starts on that PC unless a fixed one was set. After four wrong passwords in ten minutes the PC stops taking passwords from there for a while; leave the password blank and the person at the PC can still let you in with Allow.
  6. Still stuck? Write to hello@nelkira.com with the PC’s number and what the window says. Never send the password.

Lost my account key

We keep only a fingerprint of the key, so we cannot show it again. Write to hello@nelkira.com from the email address you registered and we will say what we can do. The PCs you installed keep working without it: the key is for signing in to My account, not for connecting.
