What have you tried:I’ve tried changing browsers—Chrome, Firefox, Edge, and Tor. Sometimes Chrome allows the download, but other times it doesn’t. Firefox doesn’t download at all, Edge opens a blank window, and Tor downloads the file as a PDF. I’ve also asked for help from GPT and my college group, but the only advice I get is to download it in a different format, which I already know I need to do. 
What is the error:The main issue is that the Kali file keeps downloading as a PDF instead of the correct format. Sometimes Chrome allows the download, but when I click on it, it automatically tries to download as a PDF. Other browsers either block the download or don’t work properly.
What device is this on: This is happening on an Acer Aspire A315-54K laptop with an Intel Core i5-6300U processor, 4GB RAM, a 240GB SSD, and Windows 10 Home Single Language (64-bit).
