Launcher Crashing when 64-bit Java installed

Question

The launcher will not open if 64-bit Java has been installed, even if 32-bit Java is also installed.  32-bit Java has to be the only Java present on the system.  My one and only workaround for this at the moment is to install 64-bit Java on a thumb drive and plug it in AFTER I've opened the Technic Launcher, so that I can choose it in the Java settings and increase the max RAM available.  

If 64-bit Java is installed on the system, the launcher will load for less than a second and then close, and then a Java error report will be saved where the launcher is located.  Attached is one such error report along with a log file from the .technic roaming folder.

The Java version is jre1.8.0_65.  My OS in Windows 10, with 16GB RAM.  Let me know if you need any more information about my system to tackle this issue.

Ok RivaTuner is uninstalled, but I will have to continue this tomorrow.  I'll install 64-bit Java and test it out first thing.  Thank you for the help so far.

Seems to be working so far.  I removed the thumb drive so there was no 64-bit Java present on the system, downloaded and installed 64-bit Java, rebooted, and started up Technic without the thumb drive plugged in.  I'm able to load up a modpack and play.

How did you know to remove RivaTuner?  

Thanks so much for the solution and quick replies!

Here is a Fix without removing RivaTuner:

  1. Open RIvaTuner Statistics Server
  2. Click "Add"
  3. Navigate to your Java directory f.e: (C:\Program Files\Java\Version\bin)
  4. Select "javaw.exe"
  5. Change "Application detection level" to "None"
  6. Start the Technic Launcher

sorry for adding to an old thread, but i thought it might be useful.

      I've played tekkit for a couple thousand hours now and never once encountered the battle I'm going through now. I haven't played in about 6 months or so.
      Some things to note:
      - I have both java 32 bit and 64 bit  runtime environments and I have experimented with a variety of different versions (many recommended on this forum)
      -I have 16Gb of RAM, a dedicated GPU and my nVidia driver is up to date. I have also rolled back to previous versions and encountered the same issues.
      -With any 64 bit java installed on the PC, Technic Launcher will not launch.
      -When I uninstall 64 bit java, launcher starts (in 32 bit) but obviously ram cannot be changed etc... However whilst running, I can install 64 bit java and then change ram settings.
      -Packs will download in this case however will not launch even when RAM is set below 6GB. I get a little java pop-up window saying "Hello".

      Please please please provide any assistance as I'm not ready to give up just yet!

      Hi! So, whenever I load up a modpack, it starts up minimized and never opens. It eventually loads further, and I can hear the music, but it never stops being minimized. I was able to play all of these modpacks on my old computer, which was running windows 7. Even though this computer only has an intel i3, that one was dual-core 32 bit and these packs still worked! Is anybody else having or had this problem, and can anybody help me?

      So I have the launcher options set so it can use 6GB-s of ram but whenever I try to play it caps out at 455MBs. I need some technical help with this

      When trying to play any modpack on the technic launcher, i have the options to choose anywhere from 1gb ram to 15gb ram, being that i have 16gb ram installed on my pc. The problem i run into is that if i choose any more than 6gb allocated, the modpacks wont load at all. the technic launcher will close as if it is starting the modpack then will immediately open back up without attempting to load the modpack, giving the error "Not enough memory installed to support this modpack" in the console. When i open my system properties it shows that i do indeed have 16gb ram installed. I've already tried uninstalling and reinstalling technic, each of the modpacks, java RTE, and even attempted replacing my RAM twice with 16gb Corsair Vengeance Pro with no luck. Any help would be much appreciated.

      I can't allocate more than 1 GB of RAM to my technic launcer, and before you comment you need to know that I have a 64bit Win10 and 64 bit Java 8 latest version. I also have plenty of memory available (16 more precise) and a pretty nice pc, my only problem is that I can't load any pack because of the Ram restriction
