Method #1: Check Your Internet Speed

Fluctuation of network connection or unstable internet is the major factor behind can’t play online videos or videos playing in slow motion problem.

Hence, it might possible that a weak internet connection is responsible for the “error loading media: file could not be played” issue. So, make sure that your network has good strength before you try to play an online video.

If this way won’t help you to troubleshoot this error, then try the next one.

Method #2: Delete Cookies, Cache & Browser History

Cookies and cache are just a small piece of information that is stored in directory of the web browser to provide you with the best user experience. Internet browsers like Internet Explorer stores cookies and cache to spend up the loading process.

But, as time passes by, these cookies and cache pile up in the PC creates issues like ‘error loading media file could not be played on Chrome’. So, it is important to clear the cookies and cache, and browsing history on a regular basis. To do so, you have to follow the below steps:

For PC Users

First of all, you have to open Google Chrome and then access the action menu in the very top-right corner of the screen.
Next, you have to go to the option More Tools and then select Clear browsing data.
After this, you are required to select the tab ‘Basic’ and then use the drop-down menu near Time range just to select the option ‘All Time’.
You can then check the box just next to Cookies and other site data and then next to Cached images and files. After this, simply hit the option ‘Clear Data’ in order to eliminate or delete the cookies and cached files in Google Chrome.

After the process gets complete, you have to restart the Google Chrome and then tap the action menu.

For Android Users

In the first step, you have to launch Google Chrome on the Android device and then simply tap the action menu
Next, you have to go to Settings and then simply tap on Privacy.
Now, you have to scroll all the way down and then tap on Clear Browsing Data.
After this, you have to select the Basic tab and then set the Time Range option to All-time with the use of drop-down menu. Now, you have to check the boxes that are associated with cookies and site data and cached images and files. After this, you have to hit Clear Data to delete the items.

I think your reply is not relevant to the question in the first post and you have posted your reply on the wrong forum. Upon checking the ticket option, this thread is placed in the wrong section (UI for Universal Windows Platform). I have moved it to the UI for WinForms as the question is targeting this platform. You can check which platform are you using and move your reply to the respected thread.

Hello, ATHIQ,

Thank you for writing.

I would like to ask you to carefully check the references to all Telerik controls in your project and make sure that they are the same version considering the suffix as well (.20 or .40). Better yet, you can remove all references and add them anew by using the DLLs from your fresh installation. Delete the license. file. After that, you should rebuild your project, close Visual Studio and open it again to make sure that no references are kept in the memory by Visual Studio.

I hope this information helps. Should you have further questions I would be glad to help.

Hello, Jenny,

Thank you for writing.

If you obtain such an error, this means that either the referred ddls in your project differ from the one in the license.licx file or you have installed a different version of the Telerik UI for WinForms suite. That is why I would recommend you to follow the described steps in my previous reply. If you are still experiencing the same problem, it would be greatly appreciated if you give us some more details about the used version of our suite, whether you have an installation or not, what is the available version in GAC. Thus, we would be able to assist you further. Thank you in advance.

I hope this information helps. Should you have further questions I would be glad to help.

Hi Everyone.

Thank you for reading this post.

This is very frustrating. I was running my program after installing visual studio 2019. Then I got another program from my colleague and while building the program I get the error message that Telerik.Win.Controls.UI could not load.

I see that the .dll files are in the library.

What could go wrong? Is it because of the VS 2019 version. But I was running the other old program in that same environment.

I appreciate your help.

Thanks,

Robi.
