"Update Failed" and a solution

Niall_ · October 25, 2012

IMPORTANT NOTE:

IF YOUR LOG HAS LINES LIKE THIS IN IT

Downloaded 'minecraft.jar' matches MD5 of version '1.4.2'.

[10:14:21] [sEVERE]    Starting download of 'null', with 3 trie(s) remaining

[10:14:21] [sEVERE]    java.net.MalformedURLException

THIS FIX WILL DO NOTHING FOR YOU AS IT IS A SEPARATE ISSUE

Launcher Version: 1.0.2.0

Operating System: Win7

Java Version: jdk1.7.0_07 (64 &amp; 32bit)

Antivirus Program: None.

Description of Problem:

While updating through the Technic Launcher, it will attempt to download minecraft.jar 3 times and fail with the message Update Failed!. After checking my log files I can see that the problem is that the minecraft.jar files it attempts to download do not match the md5 hashes of what the launcher has.

A solution: download Minecraft 1.2.5 from Mojang directly (url: http://assets.minecraft.net/1_2_5/minecraft.jar ), rename the file you just downloaded to minecraft_1.2.5 and place that file into your .techniclauncher/cache folder. - NOTE: If you're on windows and have enabled file extensions to be shown (the default is that they are not shown) then you will need to rename the file to minecraft_1.2.5.jar - do not do this if you are unsure. - NOTE: If you're using Internet Explorer, it will download the file as a zip file which will require you extract it (usually right click > Extract), you could alternatively download the file using another web browser such as Firefox, Google Chrome, or Opera.

You can find your .techniclauncher/cache in %appdata%/.techniclauncher/cache on windows, and in ~/.techniclauncher/cache on most linux distros. I believe the same folder would be under /Users/USERNAME/Library/Application Support/.techniclauncher/cache on OSX but I cannot confirm. - NOTE: For OSX the folder may simply be called techniclauncher without the leading period.

I have tried this and many other "solutions" over the last few days to no avail, every time I try and load it I get this message in my log file:

I am not how to fix it and was wondering if you are receiving the same error message about the mismatch MD5? Or is there a way to get the '032eedc7183acde5b75cd13f9ff2e324' file?

garbisch2 · October 26, 2012

jefferson_johnny · October 26, 2012

MLindsey · October 26, 2012

Did just wat you said and all worked well. But befor this I had tried several thing. First uninstalled antivirus. Second Reverted to Java 6.9 somthing. Third Copied the bin folder from .technic to . minecraft or something.

techdude · October 26, 2012

Ok, I am having the same problem but for the vanilla minecraft setting. I'm trying to use it as an easy way to downgrade to 1.3.2 for a server I play on. I made sure to download a 1.3.2 minecraft.jar, and changed the name to minecraft_1.3.2.jar

The errors don't change.

epicnessinacan99 · October 27, 2012

techdude you have to name it minecraft_1.2.5 so try no toutting the .jar on the end as it automatically turns it into a .jar

Trowa_7 · October 27, 2012

I did the same thing over and over again (17 times) and now it works! Thank you for your help and information.

[13:15:18] [sEVERE] Exiting the Technic Launcher

dictioncracker · October 27, 2012

for a 5 second file rename and a 6 second fix people still cant figure this out it seems . Yes this works. stop saying it does not. I helped 10+ people out yesterday and every single one of them was a renaming issue or file extension was wrong. just verify name+extension and re-run launcher.

dictioncracker · October 27, 2012

just message me i did not remove the temp skype yet

chaosxkiwi · October 27, 2012

i found the solution if it does not work for you and you get the error "Update Failed" what you need to do is also copy it into the modpack folder that you are using - C:\Users\":\AppData\Roaming\.techniclauncher\technicssp\bin like this but if you want to use hack/mine you will need the minecraft.jar 1.2.3 already posted earlier as well as the cache

Minecratnoah123 · October 27, 2012

Worked for me. Copied minecraft_1.2.5 and pasted it into the 1.2.5 downloaded jar. Then pasted it into the cache. Thanks!

infernomage39 · October 27, 2012

i just tried using the 1.2.5 minecraft jar and it ould work. i even did what the guy above me said, i have no idea what to do. the update failed is annoying all it is doing is it goes through saying download minecraft.jar and wont download tekkit >_< and im also stupid and dont understand anything so that may be the problem too.... any help pwease?

You might have another issue. Read the other sticky and see if those help.

Ben Freda · October 27, 2012

this hasn't worked for me ive tried it about 10 times and it hasn't worked. also my problem is the same but also i canot choose my mods and my cashe wont clear

Ben Freda · October 27, 2012

i just found another thing, it only says its downloading minecraftjar. on tekkit and all the other mods it just fails to download immediately

Drthaawesome1 · October 27, 2012

when i try to launch i get the message "unable to download launcher. please check your internet connection by opening www.techniclauncher.net in your browser". the site doesn't help, it still doesnt work, and i don't know what to do now

DragsZombies · October 27, 2012

OMG! Thanks for this! I just got this problem today and I didn't know how to fix it! THANK YOU SO MUCH!

Newbcraft · October 27, 2012

doesn't work for me!

_ShadowRaven_ · October 27, 2012

It works. Thanks

Caboozles · October 27, 2012

Hi, I realize how extremely vague this may be, and if there's something else you need as far as information goes, but since Yogbox seems to be demanding 1.2.3, is there a 1.2.3.jar download floating around that I could get for it?

Alanaaya · October 27, 2012

Hello people !,

Make sure u rename it to minecraft_1.2.5, and not minecraft_1.2.5.jar.

Ashzification · October 27, 2012

Hello people !,

Make sure u rename it to minecraft_1.2.5, and not minecraft_1.2.5.jar.

Regards,

Alanaaya ;3

Did you skip every other sticky just to post on this one?
