Talk:Minecraft launcher/Archive 1

Shouldn't this wait a while?
Right now this is just a bunch of speculations, the only true information we have is that it logs you in (to the game, nothing was ever said about the site) and that it displays news. All of the other stuff isn't new, like the merchandise, the facebook page, that has all been there before just not on that page but on minecraft.net. The trivia is also kind of pointless. Why does it matter that it prevents one from opening multiple pages of the news feed? There wasn't a true news feed before so it was never an issue. Let's just wait for the facts. --Flippeh 04:42, 29 January 2011 (UTC)

Page needs update?
I think that the "Updated Launcher" section is out of date. Sakishrist 10:07, 27 August 2011 (UTC)

I think it's said that the newest version the for 1.6 and later launcher could launch is 1.6.4, but there's already 1.7.2 avaible except 1.8-snapshots (there come too much, no one can update this page with that fact). I hope my English was good enough. --80.139.46.128 19:11, 26 November 2013 (UTC)

Launching minecraft.jar with C/C++
How can one launch minecraft.jar from C/C++ application? Any examples or keywords?

to launch the windows executable in c++: int main {   system("Minecraft.exe username password ip_address:port"); //system("Minecraft.exe notch notch's_password1234 192.168.0.1:25565"); return 0; }
 * 1) include

No longer possible to supply username and password via command line?
I tried following the instructions herein for logging in automatically (wanted to make a shortcut for each of my, my wife's, and my daughter's accounts) and none of it appears to work.

In January, [a StackOverflow answer](http://stackoverflow.com/questions/14531917/launch-minecraft-from-command-line-usename-and-password-as-prefix) indicated that this has been removed for security concerns. Should this page be updated to reflect that? Is anyone still successfully logging in with command-line options?

version
This page doesn't tell how to choose what version you play on. Can someone explain this? --70.181.68.226 03:18, 17 May 2013 (UTC)


 * It seems you now need to use the profile editor. That will allow you to change versions, and will narrow the drop down list by quite a bit. Firebastard 19:41, 10 June 2013 (UTC)
 * Lol, thanks. I haven't looked back here since May 28, I think. --70.181.68.226 04:40, 23 June 2013 (UTC)

JVM exceptions
With the new launcher there is a feature to use JVM Arguments. I'm sure writing a section about this under the new 1.6 launcher would be useful. Of what I know it can allow the player to change the amount of ram allocated to Minecraft. --Nelsonngyn0 05:16, 7 July 2013 (UTC)

Variable for Launcher versions
I know we have a variable, v, for Minecraft versions, though I'm not sure if we have one for the new launcher versions. Information on this would be much appreciated! -- Bb 20   (Edits)  00:55, 28 July 2013 (UTC)


 * I'm not sure what you mean. Are you referring to Version? -- Orthotope talk 10:03, 28 July 2013 (UTC)


 * Yes, that would be part of it. AFAIS, launcher versions are being tracked per MC version, though I am unaware of any version template for these launcher versions. -- Bb 20   (Edits)  17:45, 28 July 2013 (UTC)

lastlogin is gone; now launcher_profiles.json
While reporting and troubleshooting an inability to log out recently, I discovered that the launcher no longer (as of fourth generation 1.2.1) uses the lastlogin file to look for authentication information. It now depends on whether you have one or more profiles. One profile, and you can log out. The replacement for the lastlogin file appears to be launcher_profiles.json as deleting that file reliably logs out the launcher (unfortunately, by deleting all of the profiles.) Individual profiles can only be deleted by selecting the "Edit Profiles" tab and right-clicking on a profile (Backspace and Delete do not work, and there is no Delete button on the Update Notes tab's Edit Profile dialogue.)  I'm going to delete the lastlogin reference after this experience. (I've also noted that lastlogin no longer appears on fresh installations of Minecraft.) When one has a single profile, the launcher does put the login information in launcher_profiles.json (current as of 1.2.2; unknown thereafter.)  I'm going to update the main page now that I've actually seen it in action. Featherwinglove 18:52, 3 September 2013 (UTC) Last edited: Featherwinglove (talk) 17:56, 20 September 2013 (UTC)
 * When updating the main page, I decided to test all launcher behaviours on the main page and found out that almost all of them were different. Dinnerbone added "READ_ME_I_AM_VERY_IMPORTANT" to the "assets" folder, which basically says you can't hack "assets" directly and to use Resource Packs (it says the launcher synchs "assets" every time it is run, which it apparently does with libraries as well.  Whether you can hack "assets" by firewalling the launcher and always playing offline, I don't know, but I also see no point, lol!)Featherwinglove 19:38, 3 September 2013 (UTC) Last edited: Featherwinglove (talk) 17:56, 20 September 2013 (UTC)

Sneaky Updates
1.2.4
 * I haven't been able to find a reference for the 1.2.4 launcher update on the blogs or Twitter, so we don't know what changes we have from 1.2.3 to 1.2.4. I've tested for changes in the log in/log out behaviour, and there aren't any (that's part of the launcher I'm very familiar with) and Time Machine versions.  I'm not very familiar with them, but I don't recall there being Beta between 1.0 and 1.2 previously.  Are they new? - Featherwinglove (talk) 17:51, 20 September 2013 (UTC) P.S. the first IP update regarding 1.2.4 was not me.


 * I think we should personally remove it since we can not find any factual information about it. - Jonathan Jennings (netcvb) (talk) 21:24, 26 September 2013 (UTC)

Changing login details
After a couple of hours searching and mucking about with files, I have found out how to change login details for the launcher...

Just play the game.

Yes, as long as you GET AS FAR AS THE MAIN MC MENU (and exit) your local details will be updated (so you won't have to enter them every time you start the game).

Yes, I've just spent 2 hours being stumped by something that works properly.

Yes, I'm probably the last person on the whole planet to migrate to a Mojang account, and this note will be useful for absolutely nobody, ever.

I'm going to go and cuddle a creeper now :o(

Profile Game Directories
I think we need to add some information on how to use different directories for different profiles. I'll like to start it here as a "Talk" and then make a summery and put it up on the page. Please leave feedback and tell me if I need to make it more educational/fail-safe.

From my experience, this is how you do.
1. Start up the launcher (obviously).

2. Make a "New Profile" or use the one you already have, "Edit Profile".

3. In the Profile Editor:

a)Change the name to your like(optimal).

b)Check the box next to "Game Directory:"

c)Change the value to where you want to have your Profile's saves, resources, logs, options.txt, servers.dat and screenshots.

The same goes for any mods you have, that are profile specific.

An example of the folder:



An example of the value:

C:\Users\[Name of Computer]\Games\Minecraft\Client\GameDir\TutorialProfile If you have any spaces in the value you'll need quotes ( "random value" ).



4. After you're done, click "Save Profile" and start the game. You will soon see that you don't have your world(s), settings, achievements or servers. Don't freak out! We'll fix it.

5. Exit Minecraft, and launch you're new profile folder (can be accessed via the Profile Editor with the handy button "Open Game Dir")

6. Then you also need to open the original .minecraft folder. Either go to a profile that you haven't modified or click this link to that page. )

7. Copy the saves (All world(s) or just the ones you want for your profile), resources, options.txt and server.dat

(Don't move, if you don't know what you're doin'! You might lose you're world(s)! I have warned you!)

8. Restart the Launcher, select your profile. Login if promted.

9. Click Play and spread the word!

Concerning the posting of possible personal account information by 99.112.22.163
I have sent a friendly email to the person whos email was posted here by 99.112.22.163, to let that person know that their account information may have been posted and that they should change it immediately if that was correct. This is more informative, though I thought I'd mention it. -- Bb 20 (Edits)  14:30, 17 April 2014 (UTC)

Page Cleanup
I've been looking over this page and I've noticed several things about it that should be revised/removed. For example, there is still segregation between the introduction and "1.6 Launcher", which are talking about the same thing. One of our primary goals should be to make the page more organized (ex. Combining the two separate Histories.) I'm also thinking of adding an infobox, something along the lines of this. - Exhelah t - c 19:32, 16 May 2014 (UTC)


 * I've begun some of the cleanup. It looks somewhat better now. I have little clue what to do with the two histories, however. We can begin to combine them based on the dates of the new launcher version releases, matched with the respective Minecraft versions, but it will likely be very tedious and time-consuming. -108.40.203.114 06:37, 18 August 2014 (UTC)

Minecraft Launcher allowing multiple instances on same profile
I can already do that but everytime I launch another alt on the same profile I get that notice that could cause issues, but I'm using Magic Launcher with the same profile and theres no issues (IM always on Multiplayer servers so it shouldn't affect me, if in singleplayer, I would do Open LAN mode.)

Launcher Notice

^^ This notice should appear in the first time

Possible to, add an option or a onetime notice that says that like enabling snapshots or older MC versions, possible? TNTUP (talk) 02:46, 21 August 2014 (UTC)

How to get custom versions

How to update from Launcher 1.5.3 to 1.6.5?
I'm still running Launcher v1.5.3. I've been trying to update to v1.6.5, and rerunning the executable brings me straight to v1.5.3. What am I doing wrong?

EDIT: I am running what Java 8 Update 20 on a Windows 7 Home Premium computer with 2 GB of RAM. User:GunslingerN7 (Talk, Contribs) 00:27, 21 December 2014 (UTC)


 * Uninstall Launcher v1.5.3 along with the Java build that you're using. Then, download v1.6.5 here: . BDJP007301 01:04, 21 December 2014 (UTC)


 * One can use the native test launcher using the msi installation method or by downloading an exe of it, though deleting the current Minecraft launcher executable and the current instation of Java is not required. Note that the new launcher is only for testing and may not work during this period of time, happened once earlier this week. Consider too that Java is not just needed by Minecraft but web applications as well. You can safely run the test launcher overtop of the current launcher, no problem. -- Bb 20 (Edits)  03:23, 21 December 2014 (UTC)

Windows 10
Can this be run on windows 10? I'm asking because there is the windows 10 edition which is MCPE and on the history section on this page it says "added windows 10 support." I don't have windows 10, so I can't find this out on my own. --JimbobsDiamonds64 (talk) 22:04, 22 August 2016 (UTC)
