I'm attemping to get minecraft to work with 64-bit Java on Windows 8. So far I have installed the 64-bit java and the most recent update from Minecraft.
Minecraft works when using 32 bit, but I get a lot of java crashes.
I just created a shortcut to the minecraft.exe and used the following:
Target: "C:\Program Files\Java\jre7\bin\java.exe" -Xmx1024M -Xms512M -cp Minecraft.jar net.minecraft.LauncherFrame
....the "Reduced Color Mode" checkbox (in Windows 8 on the compatibility mode tab, which you have to check first before you can choose 256 colors) is grey'd out/disabled. There is absolutely no way to check that box when you have the target set to the above line.
So, this basically comes down to I cannot play minecraft unless I want to deal with java crashing every 5 minutes in 32 bit mode.
Does anyone else know of any tips? And yes, I've installed/reinstalled java and minecraft and even my video drivers many times.
If you haven't already. Uninstall java 32 bit.
If you installed 64 bit prior to uninstalling 32 bit. I'd uninstall the 64 bit version as well, and then reinstall it.
Now with only 64 bit installed just launch minecraft using minecraft.exe
(If you need 32 bit java for something, it works better if you install it after 64 bit.)
Minecraft runs using 64 bit java as a default. So with both java versions installed, minecraft will run on the 64 bit by default.
If you have given up on trying to fix your java installation so that it "just works", then you should be able to accomplish the same thing by using the Profile Editor feature of the new launcher.
Run the new launcher, select "Edit Profile" in the bottom left. Near the bottom of the next dialog will be a section labeled "Java Settings (Advanced). If necessary, click the Executable checkbox and edit the path to point to your 64bit java, i.e.
C:\Program Files\Java\jre7\bin\java.exe

Start in: C:\Users\username\AppData\Roaming\.minecraft\bin
However, whenever I try to run I get the message, "Could not find or load main class net.minecraft.LauncherFrame".
Now, I went ahead and looked that up, most people suggest using compatibility mode on the shortcut and set it to 'use 256 color'.
The only problem is, when you set the Target of the shortcut to....
"C:\Program Files\Java\jre7\bin\java.exe" -Xmx1024M -Xms512M -cp Minecraft.jar net.minecraft.LauncherFrame
....the "Reduced Color Mode" checkbox (in Windows 8 on the compatibility mode tab, which you have to check first before you can choose 256 colors) is grey'd out/disabled. There is absolutely no way to check that box when you have the target set to the above line.

Thank you for the suggestion!
