Launcher Crashing when 64-bit Java installed

[McD285]

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.

Can you uninstall Riva Tuner, restart your pc and check the game again?

[McD285]

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!

It's in the java error file. It was loading a 32 bit version of riva tuner helper libraries with 64 bit java.

[McD285]

Ah ok.  Thanks!

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.
