I had issues on Friday with Katalon, some eclipe errors that were solved in a previous post. Today, whenever i try launching a Test Case, even in debug mode, I get the following error. Any ideas? 04-29-2019 05:31:50 PM Test Cases/TC\_0031\_Verify\_Attending\_Physician\_Options Elapsed time: 1.984s Test Cases/TC\_0031\_Verify\_Attending\_Physician\_Options FAILED.

I tried Firefox, and it seems to be working. It looks like it’s slower, so I’ve had to introduce longer delays. I would be happier with Chrome if possible. I had updated Chrome to 74 today, but then I got an error message saying the Chrome version needed to be between 70 and 73. How do I update the Chrome driver? ---

Tried that out but I’m still seeing the error. When the test cases launches, Chrome briefly opens but it’s immediately closed. The error still remains: Caused by: com.kms.katalon.core.webui.exception.BrowserNotOpenedException: Browser is not opened Build info: version: ‘3.7.1’, revision: ‘8a0099a’, time: ‘2017-11-06T21:07:36.161Z’ System info: host: ‘LAP0313’, ip: ‘172.20.125.139’, os.name: ‘Windows 10’, os.arch: ‘amd64’, os.version: ‘10.0’, java.version: ‘1.8.0\_181’ Driver info: driver.version: unknown ---

I just tried Chrome myself (I normally use Firefox). My Chrome launched by Katalon was 73.n.n.n. There didn’t seem to be anything I could do to force it to update. So I opened Chrome myself, it told me it wanted to update, so I let it update. Then I ran my test again and confirmed it was using 74. So, try opening Chrome yourself… maybe it will help to pull in the correct driver? (I really am just guessing here). ---

hi @mlucia_rodriguez, Please check that you already have `WebUI.openBrowser('url')` keyword before doing anything else. Thanks. ---

@mlucia_rodriguez This looks like an issue of Katalon with chrome version 74. I followed this: [Problem with Google chrome 74](http://forum.katalon.com/t/problem-with-google-chrome-74/24023) and it worked . ---

Ok, so I reinstalled Chrome again, downloaded 74 instead of 73, and I re-pasted the driver in the folder. That worked now, thank you! Hopefully, no more issues 🙂 ---
