Hello,

I am preparing an experiment, but when I run the experiment I get the error message "WebView Load Error: Failed to set page contents! MSHTML Control/IE Security Options Issue!"
The HTML pages of the experiment are also displayed incorrectly.

I realise that Inquisit uses Internet Explorer for rendering the HTML pages. I am working on a company computer, Internet Explorer is no longer installed here. Is there a possibility to use another engine for the HTML rendering? Or do I have to use Internet Explorer for this? Since Internet Explorer is officially no longer available (https://www.microsoft.com/de-at/download/internet-explorer.aspx), this would be a problem.

Many thanks in advance!

While Internet Explorer (the full-fledged browser) is no longer available, its MSHTML WebView component still is and will remain so. That is what Inquisit 6 and below will use to render HTML. Inquisit 7 and above will use the successor (WebView 2), which was not production-ready at the time Inquisit 6 was released. There is no way to switch to another engine in Inquisit 6, WebView 2 is unfortunately not a drop-in replacement, but requires significant re-engineering.

The error itself and the misrendering of the pages under WebView is caused by security settings on your system that restrict the features of WebView and how applications are allowed to use it. Those you would have to revise and change for things to work properly.

Dear Dave,

after upgrading our PCs to windows 11 we came across the same problem that the html does not get displayed correctly.
Could you please be more specific, to which security setting is responsible for blocking webview? Our PCs are administrated by our IT department and they need would need to know which specific security setting to change in order for this problem to disappear. 
Thanks in advance and best wishes

Unfortunately, the exact causes (i.e. combination of settings, domain / group policies, AV software, etc.) aren't clear in every case, and the error code we get bubbling up from Windows does not yield useful information beyond "not allowed on this system". In cases where we were able to pin things down, settings related to Zone security in Internet Options were responsible. For example, if you're running into this for scripts hosted on a local network share, then

(1) Internet Properties -> Security -> Local intranet -> Sites -> Check "Automatically detect intranet network"
and/or
(2) Internet Properties -> Security -> Local intranet -> Sites -> Uncheck "Include all network paths (UNCs)"

may resolve the problem. In other cases, where scripts and the HTML files are hosted on our servers, adding the hosting server to the Trusted Sites may do the trick.
