I've tried installing Forge multiple times through Google Chrome and Microsoft Edge, and it never becomes an installer, it just becomes one of those blank sheets of paper/blank file icons. Right now, it's showing Winrar because I right-clicked on it and hit "open with Winrar" which then changed its icon from the blank sheet to the Winrar icon. Whenever I try to install it, it tells me that it's unsafe and I have to manually continue the download which I'm unsure if that has anything to do with it. I'm trying to download version 1.16.5. I also tried to download earlier versions too (1.16.4, 1.16.3) and they're all doing it. I tried installing from [Repost Site Removed] and [Repost Site Removed], and tried all servers.
