I will have a read of the other threads. This alone did not work for me. The other steps I had to take were: 1. Download the jar file explicitly (I.e. Select the Linux option) 2. Tell java to prefer IPv4 stacks. 3. Explicitly allocate memory for heap. I.e. In cmd, type the following java -Djava.net.preferIPv4Stack=true -Xmx1024M -Xms1024M -jar %APPDATA%\.techniclauncher\technic-launcher-latest.jar

Hey just so everyone knows: Rolling back to Java 6 worked (which is available on the Java website at http://java.com/en/download/manual_v6.jsp ).

I do think there is a problem with the networking logic. It works fine for me with Java 6.

You're asking for a lot of memory. Try change -Xmx3G -Xms2G to -Xmx1G -Xms1G

My username doesn't have any spaces in it. If it did, then I would imagine java itself would complain before any jar file was ever run, and it could be fixed with some clever use of quotation marks and slashes. All the null pointer exceptions refer to methods that attempt to fetch data, like "getMirrorUrl" or "downloadYmlFile". And when I copy over an older snapshot of my techniclauncher folder, before I grabbed the new one, it retrieves the gui, but refuses to connect to minecraft.net. To me this implies a communication problem server-side.

Is is definitely a stability issue. I have gone through numerous steps, and the problem persists. http://forums.technicpack.net/threads/freezes-on-technic-logo-at-the-beginning.26846/

freakachu, Jorcer, and GreenWolf13: The recent surge in bug reports is clearly not "random chance" or because of people with IQs "under 60", but instead is because of recently discovered stability issues with the Technic Launcher.

Launcher Version: 1.0.1.3 Operating System: Windows 7 64 bit Java Version: 1.7.0_07 64 bit Antivirus Program: MSE (Disabled, and Firewall switched off) Description of Problem: I have downloaded the jar file (Since the Technic Launcher for Windows crashes with a Has Stopped Working message). When I run the jar file, it freezes at the logo banner. I have tried reinstalling java, deleting the .techniclauncher folder, etc. I have also tried java options like -Xmx1G nd others. Error Messages: No error message. Just freezes. Error Log: [15:17:43] [sEVERE] ------------------------------------------ [15:17:43] [sEVERE] Launcher is starting....

This seems to be the theme today. Multiple users have had this problem including me, with no solution yet. The closest is to try and download the jar file directly by choosing the linux option on the download page.

Try this: Download the jar file from the website. I.e. Click download launcher and then click the Linux/Jar option. Copy the jar file to your %appdata%>.techniclauncher folder. Click the windows button, type cmd into the search bar and select cmd. In this black box, type java -Djava.net.preferIPv4Stack=true -Xmx1G -jar %APPDATA%\.techniclauncher\technic-launcher-latest.jar See if that works for you.
