Hello,
I tried to install forge today.
What I did:
1. deleted the .minecraft folder in %appdata%
2. unistalled java
3. downloaded the latest java 8u20
4. restarted my pc
5. installed latest java
6. started the minecraft exe
7. changed the profile to version 1.8.9 and started minecraft -> The 1.8.9 version was download into the .minecraft/versions folder
8. downloaded forge for 1.8.9 recommanded build "1.8.9 - 11.15.1.1722"
9. started the 1.8.9 - 11.15.1.1722-installer.jar"
10. clicked "Install client" -> The client responded "Succesfully installed client profile forge for version forge 1.8.9 - 11.15.1.1722 into launcher"
11. When I start the minecraft launcher there isn't any forge profile. Also there isn't any forge version to select in the profile settings.
The installer logfile:
EDIT1: I also tried to do that with MC V 1.10.2 and forge "1.10.2 - 12.18.1.2011 " -> Same result
EDIT2: Im using windows 10
