Game crashes after a random amount of time ingame

[xeredar 0]

Hi,

I got this weird problem. I downloaded the launcher and started the game over it (thats why the bat file doesn't work for me, sorry). Installed Optifine (yes the right version) and Rei's Minimap (alos the right version) and everythign works out fine. Except for when i am ingame, after a seemingly random amount of time, the game just closes. No error, no nothing, just crash, back to desktop and the error file gets created.

This is the header of the error code.

#

# A fatal error has been detected by the Java Runtime Environment:

#

# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x5d479fcc, pid=5064, tid=5840

If you need it, i will paste the rest of the error. I read that i had to update my graphics driver and i did, but it didn't solve the problem. In addition, I cannot change the memory allocation. If i try, MC doesn't start anymore. I found a solution for that on this forum and tried it, but the tutorial was written for windows 8 (i am on windows 7) and i didn't find the PATH variable (only a Path one) where no Java path was included.

I hope that made sense to someone. Please help ... i love this mad :/

Thanks in advance.

Are you using a 32bit or 64bit version of Windows 7? If you are using 64bit, do you have 64bit java installed? Also check Uninstall Programs in your Control Panel to see if you still have older versions of java installed as well that need to be removed. Whenever java updates, it just installs the newest version without uninstalling the old ones.

i just recently updated to 64 bit java 7 again, and uninstalled all java versions before. the only 32 bit java version i have on my system is for chrome. also, i have win7 64 bit.

edit: after reinstalling java 64 bit again and this time not installing the java 32 bit version for my browser, i could at least start tfc with more allocated ram. need more time to test for crashes

Same happened to me. Is 32 bit a problem?

[Kittychanley 1,002]

Yes, TFC really needs a 64bit system in order to run properly. It's too processor heavy.

I also get this bug, typically after about 4-5 mins of play. I am running java 1.6.0-24 (64 bit)
