Cannot download/access pre made iso's for virtual box/vmware

I’m not sure if it’s because I’m using windows 11, but when I download say for example Zaid’s pre made iso it doesn’t seem to work. I’m thinking it’s because I’m using Windows 11. Any advice I really want to get some practice in, but been having this issue for a while. This is the only and current computer that I use at the moment, but it’s windows 11 unfortunately. Thanks in advance

Are you getting any particular errors? If yes can you share a screenshot? Also which exact iso file did you download?
