Error: Invalid or Corrupt jarfile

[YouLookTasty]

forge-1.16.5-36.1.0-installer.jar- I've used this to install forge but it does not work and shows me Error: Invalid or Corrupt jarfile
 

I've tried it with every other forge version (1.16.*, 1.8.*) But the same thing shows.

 

Please help I've tried reinstalling java over a few times (uninstalling it too)

Jarfix does not work

I've installed them from this webpage in "files"

I ran the file from downloads

[YouLookTasty]

Downloads > rightclick file > open with > java > error pops up

[YouLookTasty]

I've found the solution thanks. Just had to keep downloading the installer until Unconfirmed #####.crdownload stopped showing in the downloads folder. Found it strange that on the browser it shows as a finished download.
