Issue Details

I have built a WebVI in the G Web Development Software Web Module and now I am trying to test it. I can run the WebVI in G Web Development Software, but when I choose the option to Run in Browser, the browser window opens and displays the following message:

This browser is missing features needed to run this web application. Open this web application in a supported browser.

Unable to load required dependencies. Please verify all WebVI files are available and served using an http server or use a browser that can load files directly from the filesystem.


To resolve this error, make sure that the default browser on your Windows system is set to one of the browsers supported by the G Web Development Software Web Module and not an unsupported browser, such as Internet Explorer:
  • Chrome
  • Firefox
  • Edge
  • Safari
Follow these instructions to change your default browser.

When using a supported browser, but the message is still being displayed as text while the WebVI is being displayed correctly, simply delete the message out of the HTML file body.

Additional Information

When you choose the option Run in Browser to run your WebVI, G Web Development Software will open up whatever browser is set as default on your system. If your default browser is not one of the above-listed browsers (such as Internet Explorer), then the browser will display this error message.
