Installer Tools Download Error

[WolfJaz]

I am receiving an error on 1.15.2 Forge where it shows it is unable to download "installer tools 1.1.4".

I have done nothing fancy, I downloaded the installer and launched it. Nothing much.

It also happened to be that I tried to install the  "installer tools 1.1.4" manually but it showed an error. There is a screenshot given below.

I am also sending an installer log with it.

Please help me.

Manually place the file there, if you can figure out what is preventing the download in your browser.

The otehr thing I would try is make sure you either run the installer as admin, or fix whatever permissions are messed up in your minecraft directory that isn't allowing it to download the file.

Not working. Tried giving the files permission but no options show up. I again tried downloaded  and installing the files but it shows "moved or missing". I attempted downloading on 3 different browsers, Opera GX, Firefox and Chrome. None of them worked.

Maybe its more of the sites problem. I even tried VPN but still not it.

I previously had also installed forge for 1.8.9 and it worked. It was like a year ago and it works fine till now.
