14.2 Forge won't install - process failed, invalid outputs

[Mythblood 0]

After running the forge installer (the Jar file), it gets to the end and pops this up:

 

Process Failed, Invalid Outputs

 

I have completely uninstalled, and manually deleted the .minecraft folder twice, but still get this.

I'm on windows 7, JAVA edition.

 

The installation log just has the same:

Forge version: 26.0.12

Also tried Forge version: 26.0.13

 

I also gave up, and tried to downgrade to minecraft 13.2, but ran into the same issue (with diff hashes).

 

I don't know what to do next, any thoughts?

I'm not getting this error, try deleting the files it mentions so the installer will re-download them

[Mythblood 0]

I've done that, still get the same error. I delete the entire .minecraft folder, relaunch the launcher let it download. Close and run the forge installer ...exact same error message with those exact same hashes.

 

I've uninstalled the launcher and deleted the .minecraft folder.

 

I get the launcher from: https://my.minecraft.net/en-us/store/minecraft/#owned

(followed the download link on logged in account)

 

Just get the same error.

Have you tried deleting the Forge installer and getting a fresh one?

[LexManos 1519]

Post your logs.

[Mythblood 0]

forge-1.14.2-26.0.16-installer.jar.log

 

Fresh forge file, same error.

 

I guess if no one else is having an issue something is different about my system... so why am I getting different JAR files from the minecraft launcher? what has function is forge using? is it SHA1 or something? Is it worth verifying the hash of those files manually?

My launcher version is (found by clicking on the number in bottom left of the launcher):

Next Steps?

I can see from the github this is an SH1 hash .... does this mean I'm getting a different download? from where? seriously could use some help on this. What do I do?

It means that something you're doing is producing a wrong output.

However, your input hashes are correct in the log.

So something else is wrong.

What version of java are you running?

[Mythblood 0]

java.exe -version

 

returns:

 

Quote

java version "1.8.0_51"

At this point I've just given up. This is beyond frustrating... still get the same error with 1.14.3-27.0.24

 

Is there nothing that can be done? can I get the download of forge from someplace else rather than a installer that generates the output?

No, you must use the installer.

Try updating to the latest Java 8.
