What if I get an External Protocol Request message

What if I get an “External Protocol Request” message?

Many people assume this is an error in the system. It’s not. This is Google trying to be helpful and letting you know that some action from the browser is trying to open another application – whether it be a specific action that you wanted to take or maybe something malicious in the site you’re looking at. It’s simply a warning from Chrome.

Do I need to take action when I see it?

Yes. You need to take action when you see this warning as it’s stopping you from opening PATorganiser.

Here’s what you should do:
  1. Check the Remember my choice for all links of this type box,
  2. Click the Launch Application button,
  3. Close PATorganiser,
  4. Open PATorganiser,
