Install Arqma Wallet on Windows 10 & 11

Before you start

• Windows 10 (64-bit) or Windows 11.
• About 8 GB of free disk space if you plan to run a full node; ~500 MB for remote-node mode.
• An internet connection during initial sync.
• A pen and paper for the seed phrase. (No, really. Don’t type it anywhere.)

1. Download the installer

Always start from the official download page. Do not download Arqma Wallet from search-ad links, third-party mirrors, or messaging-app forwards — those are the two most common ways people end up with a malicious clone that drains the wallet on first send.

Pick Arqma-Wallet-Setup-x64.exe. Save it somewhere you can find again (Downloads is fine).

2. Verify the download (recommended)

Each release is published with a SHA-256 checksum. Verifying takes 30 seconds and confirms the file wasn’t modified in transit.

1. Open PowerShell (Win+X → Windows PowerShell).
2. Run: Get-FileHash $HOME\Downloads\Arqma-Wallet-Setup-x64.exe -Algorithm SHA256
3. Compare the printed hash with the one listed on the download page. They must match exactly.

3. Run the installer

1. Double-click the .exe. Windows SmartScreen may show a “Windows protected your PC” dialog because the binary is new. Click More info → Run anyway.
2. Accept the User Account Control (UAC) prompt.
3. Accept the license and pick an install folder. The default (C:\Program Files\Arqma Wallet) is fine for most users.
4. Leave “Create desktop shortcut” ticked, then click Install.
5. Click Finish when it completes.

4. First launch

Open Arqma Wallet from the Start menu. On first launch you’ll be asked to either create a new wallet or restore from a seed phrase. If this is your first wallet, choose Create a new wallet. If you already have a 25-word seed from another device, choose Restore and follow our recovery guide.

5. Set a strong password

The password encrypts the wallet file on this PC. It is not your seed phrase and it cannot recover the wallet on its own. Use a unique 14+ character password and store it in your password manager.

6. Write down your seed phrase

The wallet will show you 25 words. Write them on paper, in order, with a pen. Do not screenshot. Do not paste into Notes, Slack, or email. Read more in our seed phrase security guide.

7. Let the wallet sync

The first sync downloads recent blockchain history. On a remote node this takes a couple of minutes; on a full node it can take several hours. The wallet is usable for receiving immediately; spending requires a complete sync. If sync stalls, see why is my wallet not syncing?

Common Windows issues

SmartScreen blocks the installer

Click More info and then Run anyway. This warning fires on any new executable that hasn’t yet been seen by a critical mass of Windows machines.

Antivirus flags the wallet

Cryptocurrency wallets are sometimes flagged by heuristic scanners. As long as you downloaded from the official source and the SHA-256 hash matches, you can whitelist arqma-wallet.exe in your AV. If you’re unsure, ask in our community channels.

“VCRUNTIME140.dll is missing”

Install the latest Microsoft Visual C++ Redistributable and relaunch.

Wallet won’t open after install

Right-click the shortcut → Run as administrator once. If that succeeds, the issue is folder permissions on %APPDATA%\Arqma. Grant your user account full control on that folder and you won’t need admin again.
