Would 1.6.4 mods work in an 1.7.2 modpack?


I’m creating a modpack on the Technic Launcher, and I set the client to 1.7.2

However, a few of the mods I downloaded only tout support for version 1.6.4. will they still work in the launcher? Or is there a way of updating them or a program/mod that you put in with them to make it work?

I’m using Forge 1.7.2 as well.

How to launch Technic from flashdrive


I’ve downloaded Technic to my flashdrive, as well as the JLauncher and the JPortableLauncher. I run JavaPortableLauncher.exe but it is asking which Jar file I want to run. I’ve found both a minecraft.jar and a modpack.jar within the Data folder of the JavaPortableLauncher (Which is where another forum said I was supposed to install Technic). But neither of them launch. Does anyone know how to launch this from my flashdrive?

ForgeModLoader Unable to launch


My crash log, on the Technic Console.
This is using the latest Technic Launcher (1/6/15), and with both the new and old launchers every modpack, excepting Hexxit, will not launch. The console (as you can read) is not helpful, saying only that the modpack is “unable to launch”, and it has something to do with Forge. Help please?

Launching empty 1.7.2 mod with forge closes and returns to launcher immediately


Some background: I made my own mod by mixing the recommended hexxit (1.5.2) and voltz (1.5.2). Made a server out of it and I’ve been playing with friends and family for a few months. Now I’m hoping to invite friends of friends and I’m cleaning up some of the broken features, so I’m upgrading all mods up to 1.7.2 or dropping them, planning add a few, etc. and actually registering it through the technic launcher so everyone can load it easily.

So I tried making a 1.7.2 mod with only 1 mod installed, made a few mistakes and arrived at this error once I got it (apparently) right. When I press play it closes the launcher briefly then reopens it, during which it attempted to run the mod and failed before any window appeared. Then I tried a forge 1.7.2 template (with no mods installed) and that failed the same way. So I tried downgrading to Java 7 based on some research into similar problems. Didn’t help so I reverted, now I’m back to Java 1.8.0_25.

Then I got to thinking, I haven’t had anything from the technic launcher work that’s on version 1.7.2. Maybe its that? All versions of vanilla minecraft (including 1.7.2) have worked without issue since the error started. In my mind its narrowed down to forge 1.7.2 as the problem and I don’t know where to go from here.

Here’s the log produced at .technicmodpacksmymodpacklogslatest.log

How do I make this work or should I just avoid 1.7.2? I’m out of ideas.

My tekkit classic keeps crashing!


I was playing Tekkit classic when I got horrible lag, so I did what I always do I closed it and opened it again. Then when the mojang screen came up my tekkit crashed and I haven’t been able to open it since.

My tekkit keeps crashing


Okay I would really appreciate if anyone can take their time to answer this. I love playing tekkit and I have gotten pretty good at it. My tekkit was lagging pretty bad so I did what I usually do and close it back to the technic launcher and re-open tekkit(this usually stops the lag). I just re-opened tekkit because it was lagging and now when I try to open that world it kicks me back to the technic launcher. It DOESN’T say anything like “out of memory” or any crash code it just puts me back into the technic launcher. I’ve tried opening this world probably 8 to 10 times and it keeps doing the same thing. If anyone knows why it keeps crashing please please reply.

Technic Launcher Not Downloading Modpacks


For some reason the technic launcher is not allowing me to download any modpacks. I have tried all modpacks and all that appears is a 0% in the loading bar which quickly disappears. I have tried restarting the launcher, resetting the modpacks, restarting my computer and nothing seems to work…

Has anyone else had this issue previously? There appears to be folders created within the directory but nothing else (no files).

Any help is greatly appreciated.

This is the error I get:

Severe error when trying to launch Voltz server


At first I had an issue with Voltz, as I wanted to play with a friend on a small little private server, but when I ran the Minecraft_server.jar file, it wouldn’t spawn in any of the modpack’s items stating that no such item with ID XXXX exists. So I was told to run the batch file entitled launch.bat.. After fixing the java directory issue, it gave me a couple of severe errors when trying to download a couple .jar files (scala-library.jar, deobfuscation_data…zip, bcprov-jdk150n.jar, asm-all-4.1.jar, guava-14.0.jar) So I tried to manually download them, and once I did, I wiped the lib file clean and copied my newly downloaded files into the directory. I still got the same result saying that I never downloaded the files. Any help is appreciated.

Why does my Technic Launcher crash when play any modpacks?


When I open Technic and my favorite modpack is either Hexxit or the other one with rockets (I forgot the name), I can only play it for 7 minutes at the most before it lags REALLY bad and then crashes.

I only have 32 bit java though. My computer is normally pretty fast after I get completely logged on.

Why does technic keep crashing? Could it be because I only have 32 bit java?

What are the objectives of Minecraft-Hexxit


I have been playing hexxit for a while now and I just keep raiding castles and ships and don’t really seem to be getting anywhere, besides having like 5 stacks of diamonds (which may not even be all that useful).

What is the actual objective of Hexxit? Like what is it that I should be aiming to do or make and what are the end game items? I have tried searching a bit but can’t really seem to find anything on it. Any help or ideas?
