Can't Download FF14 on PC

Hi, I'm having trouble downloading the game on the pc, I normally play ff14 on my ps4, but my brother got interested in the game and wanted to play on the pc. As I was waiting for the game to download, an error popped up saying it couldn't download the patch files.

I usually don't go straight to posting a new thread, I found other people who had this problem as I kept trying to download again and again. Everyone seemed to have their own way of fixing it but as I tried their ways it didn't work???

Please if anyone could help with more ideas or know ways to fix this problem it would be really helpful.

right-click the launcher and use "Run as Administrator" worked for me
