Java Error opening registry key

Tags:

registry

dll

runtime

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

Error opening registry key 'Software\JavaSoft\Java 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?

Make sure you remove any java.exe, javaw.exe and javaws.exe from your Windows\System32 folder and if you have an x64 system (Win 7 64 bits) also do the same under Windows\SysWOW64.

If you can't find them at these locations, try deleting them from C:\ProgramData\Oracle\Java\javapath.

You will find a folder named "Oracle" on ProgramData folder in your windows installed drive. Remove the folder. Hope it will work. In my case my install drive is C and my path is C:\ProgramData\Oracle
