Following on from the previous post about the new launcher (please read that link if you don't know what's going on), we've released a new build of the launcher today that has some important bug fixes & a very big new feature: You can now run multiple copies of Minecraft at the same time, much easier than before! It also should fix modded versions, but please let me know if you find that there's still some issues with that.

If you are getting "error 32" with the last build, please redownload it. Links are below.

Changelog

General:

• Now supports running multiple instances of Minecraft at the same time
• Can now be kept open while the game is running, letting you access things like the help page
• Now backs up launcher_profiles.json (profiles, logins, etc) before migrating settings to new launcher
• Made launch options slightly smaller, so that more of them can fit in the same space
• The button to add a new launch option is now at the top of the list
• "Keep launcher open" and "Show game log" are now separate settings
• [Bug fix] Fixed running modded versions. Please let us know if you have any further issues with this.
• [Bug fix] Resolution settings should now work properly
• [Bug fix] Fixed an issue where opening the game directory would give an error message even when it worked
• [Bug fix] Pressing "Del" in input fields no longer removes the rest of the line
• [Bug fix] Pressing tab on the news page no longer messes with the news carousel
• [Bug fix] Fixed a crash that would sometimes happen when the game closed
• [Bug fix] Selecting input with your mouse and hitting backspace on the keyboard should now properly delete the input
• [Bug fix] The version information page no longer selects all text when you click it

Windows:

• Running the launcher from a non-C drive should now work. We're aware there's still lingering issues with running the launcher at all for some users.
• Clicking the .exe again while the game is open now brings back the launcher window instead of doing nothing
• [Bug fix] Fixed an issue with the self updater. Unfortunately, this may mean that you'll have to redownload the new launcher to get updates.

Linux support is still underway. We're getting very close – the launcher works, but we're not yet done with distribution.

Download links

Due to a bug in the update script of the last launcher, you'll need to redownload it to get the new version. Trying to update (on Windows, at least) will give you an error about failing to move files.

• Windows: http://ift.tt/2fcBfOk
  • Extract it to somewhere before running. It will make a bunch of files in the same directory as the exe!
• OSX: http://ift.tt/2fveuc5
  • Mount it, drag it to your application directory.
• Linux: almost ready, but not today sorry!

"I get a problem moving Minecraft_staigng.exe with error code 32, what do I do?"

Read the above please! Delete your current exe and redownload it from the above link.

"I found a bug. What do?"

Please leave a comment with the following:

1. The launcher version number (The bottom left corner. See this screenshot for reference.)
2. What you did, what you expected to happen, and what really happened. ("I clicked on play and thought it'd play. It blew up.")
3. A gist of the following files, found in either your .minecraft directory or next to the executable:
   • launcher_log.txt
   • nativelog.txt
   • nativeUpdaterLog.txt (may not exist. It's ok if it doesn't!)

"I didn't find a bug. What do?"

Tell us your feedback! Even knowing that it works at all is a very good thing. Like it or hate it, just let us know what you think 🙂
