Hi Chris,

Glad you found a solution!

Just wanted to point out that we recommend using the Native Browser Recorder as the main method to spy web elements.

Most of the features within Selenium are also present in Native Browser, except for the commands exclusive to Selenium like Execute Script and Switch Browser Frame. Moreover, Native Browser commands provide more tab functionality like the ability to open, activate, close and refresh a tab. As well as the ability to attach to an existing web session, send keys to a specific field and inject Js script.

We recommend using Selenium if the process requires an isolated instance, as Selenium will always create a web session free of cookies and cache. Since Native Browser commands communicate through the OpenBots extension, it opens more opportunities to our development team to build on top of these commands and add requested functionality.

I found a solution. I needed to install this x86 Update for Visual C++ 2013 and Visual C++ Redistributable Package

Then it worked.
