Java runtime environment path issues
I've had a problem with my Java installations for quite some time and I've never had time to sit and try to fix this problem.
So I went ahead and uninstalled all the various versions of Java I'd installed to get Weka to work.
I then went ahead and installed JDK v7u71 x64 (my machine is a 64bit one).
I added the bin directory of this newly installed java to my PATH.
I go to the command prompt and type in 'java -version'. Here, I'm greeted by the same old error messages:
"Error: loading: C:Windowsjrebinmsvcr100.dll
Error: loading: C:Windowsjrebinclientjvm.dll"
- Then I ran this command: '"C:Program FilesJavajre7binjava" -version' and the correct version comes up.
I went and looked at the jre directory within the Windows directory and it had an msvcr100.dll there and a jvm.dll. Why is that particular 'java' not working? and what do I have to do to get java to work correctly on my system?
One solution was that I renamed (removed) the Windows jre folder and tried the 'java -version' command. It worked. But I'm not sure that's the best solution to my problem.

after you change the PATH, type PATH<ENTER> to see the new path that the command prompt sees. If you change the path in windows GUI then you need to open a new cmd prompt to see that changed path in action in that command prompt. If you change the path variable within a command prompt then it'll only be true for that command prompt. Ultimately, run PATH<ENTER> to see the path. IF you enter JAVA and it runs the one in your windowsjre directory then that windowsjre directory is in your PATH. So try opening a new command prompt / changing your path properly.

The correct solution would have been to edit your PATH environment variable, such that is does contain C:Program FilesJavajre7bin
but not C:Windowsjrebin.
You said you added the new one, but probably you did not delete the old path.

I added the new one after checking if the PATH had the old one. It wasn't there. Still gave me problems. I checked again.

There are no other JRE folders on my system. There's a java.exe in the jdk folder in Program Files/Java/jdk<ver> as well, but I don't think that's causing problems.

@SiddharthKumar run PATH<ENTER> to see your path. You might be OK deleting that windowsjre java though perhaps it'd have been better to look into reinstalling the jre that is there but many people don't want the java jre there on their system or if it's there they disable java in their browsers.. cos java appets are apparently not very secure
