How to Set Up Portable NVDA on a USB Drive Carrying your assistive technology with you ensures accessibility on any computer you need to use. NonVisual Desktop Access (NVDA) is a free, open-source screen reader for Windows that allows you to create a portable version on a USB drive. This setup lets you plug your drive into any Windows PC and start using NVDA instantly without installing it or modifying the host computer’s registry.
Here is a step-by-step guide to setting up and running portable NVDA. Prerequisites Before starting, ensure you have the following items ready:
A USB Drive: A standard USB flash drive with at least 100 MB of free space.
A Windows PC: A computer running Windows 7 SP1 or later to perform the initial setup.
NVDA Installer: The latest version downloaded from the official NVAccess website. Step 1: Download the NVDA Installer
Open your web browser and navigate to the official NVAccess download page.
Click the Download button to save the installer file (usually named nvda_year.version.exe) to your computer. Step 2: Create the Portable Copy
You do not need to install NVDA on your local computer to create a portable version; the standard installer handles this process directly.
Insert your USB drive into an available USB port on your computer.
Locate the downloaded NVDA installer file and double-click it to run the setup.
NVDA will start speaking automatically and present a license agreement screen. Check the I agree checkbox (or press Alt + A).
Instead of choosing install, click the Create portable copy button (or press Alt + P).
A dialog box will appear asking where to save the portable copy. Click Browse… and select your USB drive directory.
Click Continue. NVDA will copy all necessary files to your flash drive.
Once the process completes, click OK on the success dialog box. You can now close the main installer. Step 3: Run NVDA from the USB Drive
Your portable screen reader is now ready to use on any compatible Windows machine. Open the file explorer and navigate to your USB drive.
Look for the folder where you saved the portable copy (or the root directory if you saved it there).
Double-click the nvda.exe icon (or select it and press Enter).
NVDA will launch, load your settings, and begin reading the screen.
To exit NVDA at any time, press NVDA Key + Q and choose Exit.
Note: The default NVDA key is usually the Insert key or the Caps Lock key, depending on your preferences. Step 4: Optional – Enable Auto-Start (Using Autorun)
If you want NVDA to launch automatically when you plug in the USB drive, you can create a basic autorun file. Please note that modern Windows security settings often block automatic execution, but it remains a helpful shortcut on managed or personal machines. Open Notepad on your PC. Copy and paste the following text into the document:
[Autorun] Open=nvda.exe Action=Start NVDA Screen Reader Label=Portable NVDA Use code with caution. Click File > Save As. Change the “Save as type” dropdown to All Files (.).
Name the file autorun.inf and save it directly to the root directory of your USB drive. Crucial Maintenance Tips
To keep your portable NVDA running smoothly, keep these quick tips in mind:
Update regularly: Run updates from within the portable version via the NVDA menu (NVDA + N) under Help > Check for updates.
Eject safely: Always use the Windows “Safely Remove Hardware” option before unplugging your drive to avoid corrupting your settings file.
Keep a backup: Copy the NVDA folder from your USB drive to your cloud storage or local hard drive occasionally so you never lose your custom configurations.
