Minecraft Forums

I play Minecraft (Launcher version 1.5.3) on a 64 bit version of Windows 7. I can launch and play the game when I am using 32 bit Java (8u25 current as of 10/21/14) but whenever I try and install 64 bit Java, Minecraft (Including FTB, Technic, ATL, etc...) can not connect to the internet. I have tried using 7u55(64 bit) which I used for months before I took a break from Minecraft with no issues (Reccomended version from FTB launcher) and also tried using 8u25(64 bit) which is the newest update. If I uninstall the 64 bit, Minecraft can connect once again.

In Vanilla MC with 64 bit JRE installed I get the error:

Any help anyone can give would be appreciated.

(Yes, I have tried deleting and re-installing Minecraft and both versions of Java as well as disabling firewalls and security services)

Did you say that a previous version of java for 64 bit worked?

Java JRE 7u55(64 bit) worked without flaw for months before I took a break from MC. It doesn't work anymore.

Did anything change during that period?

Not to my knowledge, however something is clearly different.

Try running an older version of the game in your launcher to see if that still happens.

It still happens. Any ideas what the problem is based on the log?

Can you go to your .minecraft folder find the logs folder and find latest.log and open and paste it here?

That has no information about the connection errors while launching, it is the log I have from playing the game with 32 bit.

The only log that is of use is the one in my original post.

This is an issue further than my knowlage of the java language, I will research this and get back to you if I find anymore information. If someone were to leave off from where I have that would be amazing.

Open Start and type in search CMD and then right click that and Run As Administrator.

Then type this in the CMD window.

netsh int ip reset

Done, What did/was that supposed to do.

Well to say did you try launching again.

That command resets the WINSOCK layer.

If it did not fix the issue. Uninstall java, and reinstall latest Java 7.

No luck. I can still play when im using 32 bit only but not when I have 64 bit Java

If you have 32 bit java installed as well. Uninstall forms of java and reinstall starting with 32 bit offline and then install the 64 bit offline.

If problem still exists. may need to uninstall all java and remove all traces of it.

Whats the difference between the Online and Offline versions?

Time saving. Online one just downloads the offline one. Really pointless and stupid to say. Only useful probably for net installations across multiple systems via network deployment.
