Question

why do I get this? How can I fix it?

Error: Registry key \'Software\\JavaSoft\\Java Runtime Environment\'\\Cu         


        

Answer 1

You could be using a 32 bit version of java on a 64 bit environment. Export the registry hive form HKLM\Software\JavaSoft and import into HKLM\Software\Wow6432Node\JavaSoft. For 1.6 I only needed JavaHome and RuntimeLib values.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Javasoft]

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Javasoft\Java Runtime Environment]
"CurrentVersion"="1.6"

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Javasoft\Java Runtime Environment\1.6]
"JavaHome"="C:\\Java\\jre"
"RuntimeLib"="C:\\Java\\jre\\bin\\client\\jvm.dll"
