4. Can I have a list of KnowBe4's No Prompt Domains?

For security reasons, we can not share a list of our No Prompt Domains. Additionally, since the list is constantly changing, the data on the list would become outdated quickly.

5. My users are clicking Continue but their browser window isn't appearing.

The browser window will not appear as a pop up on the screen after clicking, so it has most likely been opened. Depending on the default browser, there may be a flashing browser icon in the taskbar indicating a new link has been opened. Instruct your user to double-check their browser after clicking the Second Chance prompt to continue to the website, as it should have been opened.

6. After installing Second Chance, I'm getting an error when I open Excel.

The error message The program can't start because MSVCR90.dll is missing from your computer. Try reinstalling the program to fix this problem is due to a known compatibility issue with Windows 10, Excel 2010, and Sophos/Hitman Pro.
