This was the output of the console log when I tried to install minecraft forge 1.7.10 in a server. But when I posted the issue, two people told me forge 1.7.10 was discontinued in this forum. So I decided to try with the 1.12.2 version of forge. But same result. When I try to install server in a folder, everything OK. But when starting to install server.properties, the output was the same, but instead of 1.7.10, it says 1.12.2.

Minecraft version: 1.12.2 (obviously)

Forge version: the recommended one I think

1) THats not a Forge log

2) That just says that it couldn't find the file. So either you dont have access to read that file, or it doesn't exist.

3) That's 1.7.10... stop.

1) I want to say that log appeared when I tried to execute Forge in server mode in 1.7.10 (minecraft_server.1.7.10.jar), but when I tried to execute minecraft_server.1.12.2 when I updated my minecraft forge version, the same but changing 1.7.10 to 1.12.2.

2) How can I enable access to read the file with jre1.8.0_151? I'm the administrator of my computer.

 

So please forget about 1.7.10 version. Just imagine that 1.7.10 changes to 1.12.2.
