Hello Leela,

Do you know if you have Enabled JAB on your resource? If not, could you please try the following;

Open Control Panel
Select "Ease of Access Center"
Select "Make it easier to focus on tasks"
Check the setting "Enable Java Access Bridge"

You could find related documents on the on JAB Guide that Blue Prism has at its disposal.

Kind Regards.

Hello Leela!

It is kind of hard to know where the error is without knowing all the things that you've already tried. Once I was having the same error as you, even when JAB was activated (I did that through the Check Box in the control panel), it did not recognize any element. So, after many attempts, what worked for me was not using the 'Navigate:launch' stage to launch the application. Instead, Use the "Utility - Environment:Start Process"

I'll show you the step by step that worked for me.

Even if you're not going to use that exe path, just put it in. For some reason when left in blank, didnt work. The other prompts are needed depending on the type of the application, so ill skip that for now. On the other hand, the flow is as follows;

'Start process' will require 2 inputs paramenter. The application (exe file) and the argument, in my case was the server where the app was running. With the same utility, check for the window title, this will allow the action to wait until the window is properly displayed, sort of a wait stage.

If window is found, then attached. in my case the only input that I wrote on the navigate stage was the process. After that, all elements were able to spy.

I hope it helps but if not, remember that in some cases you can go on the support center or even create a ticket where a specialist could help.

Kind regards Leela.
