Unable to download files from WebBrowser control in Windows 10 (Version 21H2)

Question

Unable to download files from WebBrowser control in Windows 10 (Version 21H2)

CP ,QNA C 1

Hi,

We have a winform desktop application with .net webbrowser controls.
We are trying to download a .csv report from the website which is loaded inside the webbrowser control.

We are able to download the report while running the above app in Windows 10[Version 1909 (OS Build 18363.2274)]
But nothing gets downloaded while running the above app in Windows 10[Version 21H2 (OS Build 19044.1766)].

Can you please help us to identify why we are unable to download files in Windows 10[Version 21H2 (OS Build 19044.1766)] ?

Note: We noticed IE browser is missing in Windows 10 [Version 21H2 (OS Build 19044.1766)]. Will this have any impact on download functionality?.
We came to know that .net webbrowser control will still be supported even if IE removed from the OS.

Thanks

Hi @CP ,QNA C ,

Based on your description, I'm not sure if this issue is related to the missing IE browser you mentioned, because in my machine, IE browser still exists, both in windows 10 21H2 (Build 19044.1766) and windows 10 21H2 (Build 19044.1826) . Please check it. Just enter turn windows features on or off in windows search, and open the Windows feature panel to check if Internet Explorer 11 is enabled. Something like this screenshot:

Hi @CP ,QNA C ,

How did you download the file? Download via a link in the page or via a method in the WebClient class?

You can also check the following settings to see if they work for you:

Open Internet options in IE 11.

Go to Security tab.

Under Internet zone, click Custom level.

4. Scroll down and enable File download and Active scripting.

5. Click OK to save the settings.

Hello

Thank you for your question and reaching out. I can understand you are having issues related to Unable to download files from WebBrowser.

Please try to download files from Different browser or from Edge .
Please Disable any Antivirus program or Windows firewall you may have for temporary purpose.
IF this is custom browser control you have developed then try to enable and check verbose logging.
