Problems with Java when installing Minecraft
emmalee last edited by
I'm trying to install Minecraft on a new computer, but whenever I try to run Minecraft.exe I get a message that says "The registry refers to a nonexistent Java Runtime Environment installation or the runtime is corrupted. The system cannot find the path specified." I tried reinstalling Java, automatically removing the old version, but I still get this error. How can I fix this?
The following should work for windows:
Go to Start>Run>cmd.
java -versionand press return.
You should see something like this:
java version "1.7.0_05" Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Make a note of the second number on the second line (eg:
java version "1.7.x_xx"--> 7.
64 bit only: Check whether you're using a 64 or 32 bit version of java by looking in
C:\Program Files (x86)\for a folder called
Java. Inside this folder there should be another which corresponds to your version number above. This should be
?is 7 in this case. If you cannot find a
jre?folder in the
Program Filesdirectory, then you do not have the 64 bit version of java installed. Go here and grab the Windows 64 bit version, then install it.
Windows XP: Right click on My Computer, select Properties, then select the Advanced tab.
Windows Vista or 7: Right click on Computer, select Properties, then click on Advanced system settings.
Click Environment Variables.
Under System variables click on New.
JAVA_HOMEas the Variable name and
C:\Program Files\Java\jre?as the Variable value, where
?is the version number from earlier (7 in this case).
Click OK to close all the windows, then try running Minecraft again.
