So after the 1.6.0 update, I have been getting the error message saying "This application requires Java Runtime Enviroment 1.6.0." when i click on the minecraft launcher. It also directs me to a java website to download java which i did but it doesn't work.
I don't know if anyone is still having this problem, but I was earlier on my win 7 laptop. So, Seodoori was half right. If you just download both 32 and 64-bit versions JRE 6, it should work. You shouldn't even have to restart your computer. Hopefully this helps if anyone is still having this problem~
Just in case somebody is still having this issue. All I did was go into "Control Panel" then "Programs" then click "Uninstall a Program". In this section you should find a verson of Java named "Java(TM) 7 Update". You might also find something that looks like "Java(TM) 6 Update". You should delet the "Java(TM) 7 Update" file and keep "Java(TM) 6 Update". Minecraft need to run on the java 1.6.0 so that is why you are keeping the "Java(TM) 6 Update" file, and not the "Java(TM) 7 Update" file. If you dont have "Java(TM) 6 Update" you should refer to: http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html for a download. Hope this helped!
You don't have to do any of this stuff. All you do if MC says you need Java Runtime Enviroment 1.6.0, go to your control panel, then programs and uninstall all java you have. Then go install the latest Java just finished myself .
So, I tried running the default windows Compatibility check and it said I should use the Windows XP service pack 2. So I tried a test run and it didn't even install Minecraft. (I can't install Minecraft because I need Runtime environment 1.6.0) So I am trying TheCyberBunny's theory. Please keep me up to date.
I did have this problem before but an easy way to fix this is to go to the java website and download the latest version. When your in your downloads folder it will be called chromeinstall-7u60.exe, open it then run it then your minecraft will work again
