Install Vyapzio on Windows, step by step

#Before you start

• Windows 10 or Windows 11, 64-bit. To check: press Windows + R, type winver, press Enter.
• A licence key of the form VYPZ-XXXX-XXXX-XXXX-XXXX. It is in your purchase email and in your dashboard. The app installs without one but asks for it before you can use the books.
• Internet for the download and the first activation. After that Vyapzio works offline for up to 30 days between checks.
• About 400 MB of free space.

Not licensed yet? Buy a licence first. There is no free version and no trial.

#Step 1: Download the Setup program

1. Open the download pageOpen the download page and click Download for Windows. The file is called Vyapzio-Setup-version.exe.
2. Wait for the downloadEdge or Chrome shows it at the top right or bottom left of the window. Do not close the browser until it finishes.
3. Open your Downloads folderClick the folder icon next to the download, or press Windows + E and choose Downloads.

Download only from vyapzio.in. Copies from other websites, WhatsApp forwards or video links are not ours.

#Step 2: If Windows shows "Windows protected your PC"

Vyapzio is not signed with a paid Windows certificate, so the first time SmartScreen shows a blue box. That message means "this program is not signed by a paid certificate"; it does not mean a virus was found.

1. Click the small link More info.
2. Click the button Run anyway.

If the file will not open at all, right-click Vyapzio-Setup-version.exe, choose Properties, tick Unblock at the bottom, click OK and double-click it again.

If your antivirus deletes the installer, add the file or the Vyapzio folder to its exclusions, then download it again. More in Is the install safe?

#Step 3: Install it

1. Double-click the Setup programIt opens a normal Windows installer.
2. Choose the folderThe default is fine: Vyapzio installs for your own Windows account, with no administrator password and nothing added to Windows itself. You can change the folder if you keep programs on another drive.
3. Click InstallIt copies the app, adds a Vyapzio shortcut to the Start menu and, if you leave the box ticked, to the Desktop. It takes under a minute.
4. Click FinishVyapzio opens in its own window. There is no browser address bar and no separate server to start.

#Step 4: Create the owner account and activate

1. Create the owner accountThe first screen asks for a name, email and password. This account is stored only on this computer and controls who can open the books.
2. Enter the licence keyThe activation screen asks for the key from your purchase email, in the form VYPZ-XXXX-XXXX-XXXX-XXXX. Paste it and click Activate this computer.
3. Check the confirmationThe app says the licence is active and shows the computer as the first device. The key stays on this computer, scrambled, in Vyapzio's own settings folder.

No internet, or the server is unreachable? Activation needs a connection once. Check the connection and try again; if it still fails, email contact@vyapzio.in with the key and the message shown. After activation, the app keeps working offline for 30 days before it needs to check again.

#Where your books are kept

Invoices, clients, products, purchases and settings live in one folder on this computer:

%APPDATA%\vyapzio\books

Saved PDFs sit in the same folder. Nothing is uploaded by itself. The folder is not encrypted, so protect your Windows account with a password. Back it up from Settings → Backups; see Backups.

#Every day after that

Open Vyapzio from the Start menu or the Desktop shortcut. The window reopens at the last screen you used. Closing the window quits the app; your books are saved as you go.

Four people can use one set of books on this computer, each with their own sign-in and role. See One licence, one computer for the difference between users and devices.

#Removing the app

1. Back up firstIn Vyapzio, open Settings → Backups and export a backup. See Export and import.
2. UninstallOpen Windows Settings → Apps → Installed apps, find Vyapzio, click the three dots and choose Uninstall.

The uninstaller removes the program and its shortcuts. Your books in %APPDATA%\vyapzio\books are left in place so a reinstall finds them; delete that folder yourself only if you want the data gone. Uninstalling does not free the licence: use the dashboard or the same computer to activate again.
