dll - Java Error opening registry key

Question

I get this error when I try to do anything with Java in command prompt:

Error opening registry key 'SoftwareJavaSoftJava Runtime Environment.3'
Error: could not find Java.dll
Error: could not find Java 2 Runtime Environment

I did screw around with deleting Java directories and registry a few days ago. I restarted computer and java was still working fine, then i restarted it again today and now I get this error. I have tried uninstalling and reinstalling but that doesn't seem to work. I have the latest java JRE installed and the path set in the environment variables. Anyone have any clue how to fix this?

Answer 1

Make sure you remove any java.exe, javaw.exe and javaws.exe from your WindowsSystem32 folder and if you have an x64 system (Win 7 64 bits) also do the same under WindowsSysWOW64.

If you can't find them at these locations, try deleting them from C:ProgramDataOracleJavajavapath.
