Tekkit requires a downgrade patch when you are doing a fresh install. The current downgrade patch is from 1.4.5 to 1.2.5. The problem is, the launcher always pulls from the newest release, which was released today, which is 1.4.6. So we have to wait until the launcher folks update the 1.4.5 patch to 1.4.6 which normally takes about 12 freaking hours.

This is the same problem that always comes up when Mojang puts out a new version of minecraft. Basically, a new version of Minecraft was released, which means the Minecraft 1.2.5 patch that it has to apply will not work since the newest version is 1.4.6 and the patch is made for 1.4.5.So we have to wait for someone to fix the patch to 1.4.6 so that way it will work. It is annoying as heck. I STILL do not understand why the launcher just doesn't pull from the mojang's assets folder on minecraft.net, which has 1.2.5.

This is what I figured. Updated to Java 7. Same issue. As you stated, technic launcher has a funky way of going about binaries. Apparently it downloads the latest and uses a downgrade add on instead of grabbing the associated binary from minecraft.net. I know you can get 1.2.5 from assets.minecraft.net/1_2_5/minecraft.jar but even when you add it to the tekkit bin folder, it does not recognize it and continues to try and download the latest .jar, which the launcher does not recognize.

Launcher Version: 1.0.1.3 Operating System: Windows 7 SP1 Java Version: Java 6 Build 37 (Have had this build for weeks and has worked up till yesterday) Antivirus Program: AVG (Yes, it is disabled) Description of Problem: Upon starting up the Technic Launcher, I attempt to log in (and download) Tekkit, as I do regularly. However, it cannot and will not download Minecraft.jar (assuming it is 1.4.5 issue). It will attempt this three times before it says "Download Failed" Error Messages: Download Failed!
