We always make sure to thoroughly test our resources before making them available on the Twinkl website. However, not all computers and devices are the same. This is especially true in school settings, where your computers and devices may be set up differently than at home. If you encounter difficulties using our PowerPoints on a school computer or device, the best first step to take is to speak with your school's IT technician. This is especially important if the resource works for you at home but not at school. If you are using Twinkl as a home user or if your school's IT technician is also experiencing problems, please try the following: If you can see videos but there is no sound, check if your audio is working for other things that you would normally expect it to work for. Most sound issues are related to a general problem with playing audio. You can try playing a video or audio from your preferred news website to ensure that your audio is working properly in general. Once the resource has finished downloading, make sure to fully unzip all the files and save them in a central location, such as your 'Desktop' or 'My Documents'. To do this on a desktop device, right-click on the 'Download' button on the resource page and select 'Save Link As...'. Then, go to where you saved the resource, right-click on it, and select 'Extract All...'. Running the PowerPoint from inside the downloaded zip file is not supported and may not work as expected. If the sound and video files are available separately, they must be saved in the same location as the PowerPoint. When you open the unzipped PowerPoint, if prompted, you will need to 'enable content' and 'enable editing' (in the yellow pop-up bar). Otherwise, dynamic content such as audio and video will not work. If the videos are not working in preview mode, please try playing them in Slide Show mode. Click on 'Slide Show' and then either 'From Beginning' or 'From Current Slide'. (The keyboard shortcut for this is to press Alt+S and then B - the presentation will go into full-screen mode.) If you continue to have problems with videos or audio in our PowerPoint resources, please get in touch with TwinklCares and provide a link to the resource, as well as details on what happens when you try to use it.
