[Solved] [1.16.4] Can't install Forge server


Recommended Posts


I get the following error while trying to install a Forge 1.16.4-35.1.32 server in a local folder on my desktop. Also tried to install 1.16.4-35.1.13 to see if it was version specific, but got the same error.


Failed to run processor: java.io.FileNotFoundException:C:\Users\Luujauhe\Desktop\serv\libraries\de\oceanlabs\mcp\mcp_config\1.16.4-20201102.104115\mcp_config-1.16.4-20201102.104115-mappings.txt (Accès refusé)
See log for more details.

A few precisions:

  • Folder (named "serv") was empty before install.
  • "Accès refusé" is french for "Access denied" (in the above quote)
  • Client version installs just fine from the same installer
  • I can't use a newer version because of optifine.

Thank you in advance for the help

Yep, that was the issue. Avast was in silent mode, and thus didn't show the pop-up message saying it blocked the installer. I don't really know why Avast considered the "serv" folder a "protected folder", because I just really created a new empty folder.


(And on the topic of running multiple AV softwares, Windows Defender delegates the job to any other AV it detects, so I think I'm fine. Besides I don't think it's possible to entirely disable Windows Defender as it is part of Windows 10) But this is off-topic on this forum 😁


Anyways, thank you for the help
