Help! Modpacks open and immediately close on Technic Launcher!

[porky110]

Ok, so I downloaded Hack/Mine version 6.4.6 and I have done everything to try to get this to work. When I click the "play" button, the modpack opens up for a split second, closes, and then the launcher re-opens. I'm almost positive this is a problem with the launcher not downloading/installing files correctly. Also, I have two other friends that have downloaded the same Hack/Mine version, and they can play it. Here is what I have done to try to fix the problem:

1. I have reinstalled the modpack several times. This does not work.
2. I have deleted my .technic folder and reinstalled Technic at least 3 times. This does not work.
3. I have reinstalled Java and made sure I am using the correct version. I am on Java 8 V 40. I tried running the modpack on 32 and 64 bit.  This did not work.
4. I had my friend send me his Hack/Mine folder, and replaced mine with his. This did not work. 

Here are the console logs when I try to run the modpack:

​

As you can see, the jar was missing the version.json. So I went into the bin folder, found the version.json (which was not in the jar) and I copied it in there, and after that, it removed the first error, but everything else was still there, and it didn't work. One thing that caught my eye about the ​log was "[B#283]  Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0"

 

​Extra Info: I am on Windows 8.1, 8GB RAM.​​ Also, I can play any Hack/Mine version 6.4.2 and under.

 

​If anyone has any solutions to this, please reply, I really​ just want to play Hack/Mine with my friends!

I have a similar problem. I tried creating my own modpack and it was working just fine. I installed but when I hit play, it tried to start the modpack but then immediatly closed it and re-opened the launcher. No idea how to fix and could really use some help.

Ok, I have had a problem like this before, and here is my suggestion, if you have any other java than 7, delete that java completely from your computer, then install java 7, I had a problem like this, and hopefully this should fix the problem.

Ok, I have had a problem like this before, and here is my suggestion, if you have any other java than 7, delete that java completely from your computer, then install java 7, I had a problem like this, and hopefully this should fix the problem.

​I uninstalled Java 8 and then installed Java 7 Update 75, tried to launch the modpack but the issue is still there. Is there a specific Update of Java 7 that works?

[B35X]

Sadly I am not sure, this problem was solved for me when I tried that, but this may work on a case by case basis, I used the same java, but it is probable that you have a different problem than me. This is probably because of that my problem was a java version problem. A mod will hopefully take a look at this and be able to help you out.
