Ftb launcher won't load modpack

[TheMightyPickaxe]

So I was happily playing ftb unleashed when I decided to get a texture pack so I downloaded the ftb faithful and it was very laggy so I got optifine. it worked fine until I started running out of memory very quickly so I downloaded java 64 then when I tried to launch the game is said error: could not find or load main class 34. so assuming having multiple javas messed it up I uninstalled the java 64. yet it still gives me this error. I even tried re-downloading it still doesn't work. I have tried everything that I have found to no avail please help. (can't paste log because on phone but I will when needed)

Welcome. Having two versions of Java is not recommended. Could you follow this guide, remembering to backup your save and configs. Once done run the pack to make sure it will not give you an error. Then add Optifine and the texturepack. If you are still experiencing problems please post a console log in debug mode to pastebin.com and link to it here. Look here for more info about the logs. Posting it to pastebin.com is easy just click on the button 'Paste my log to pastebin.com' and in the log will appear a link that you paste here.

Since my other mod packs that run off java like Hexxit are working fine java may or may not be the problem but here is my log.

Error: Could not find or load main class 34[DOUBLEPOST=1381516180][/DOUBLEPOST]Also I have uninstalled java 64 the moment i started having the problem. btw thx for the help

The launcher is still using the 32bit version of Java. Also it is running the older version of 32bit as well. If you made a backup of your save and configs, then I'd remove all versions of Java and download the 64bit from here. Be sure to remove all traces of Java you can from your system and Uninstall program list in your Control Panel.

I i remove the 32bit for the 64bit will all programs that use the 32bit still work properly?[DOUBLEPOST=1381518598][/DOUBLEPOST]And i didn't make any backups i don't really care about my world being deleted it was just a test one i kinda just want to get back up and running. also i didn't change the configs so those should be alright

 

[lavarthan]

You should only need the 64bit version as if I recall correctly it should include libraries for the 32bit version as well. The only problem might be if you use Java in your browser as then you might need a 64bit browser, there are not a lot of them, or the 32bit version of Java as well. Most likely unless your bank requires it, I've heard some non-US banks use it, you should be able to do without it. Also make sure you do not confuse Java with java script they are completely different, most sites use java script not Java.

Here's a tip:
You should uninstall Java 32 bit completly and only leave 64 bit Java. There are no Java programs that use 32 bit Java and can't use 64 bit...
However, browser that are 32 bit use 32 bit Java. So if you want to play Minecraft in your browser you should get both and then use Jarfix: http://johann.loefflmann.net/en/software/jarfix/index.html#Download
Just put Jarfix on desktop, then use command prompt:

cd Desktop
jarfix.exe /64

Thus, you get 32 bit Java for your browser and 64 bit Java for Minecraft/FTB.
(I also posted this fix more detailed on this page - just scroll down)

Sorry it took me so long So i did what lavarthan told me but it still gives me the same error(what now) GuildMaster I will do that if i have problems with browsers
