I want to make default version of jdk 1.6 on my computer. I am using windows 7 .

Please Help.

Answer 1

While instalation Java exe files are copied to windows System32 folder, Check this location( C:\\Windows\\System32 ) java.exe, javaw.exe and javaws.exe are available there.

What you need to do now is, replace this exe's with jdk 1.6 exe's and open a new command prompt and check the version.

Answer 2

First of all be sure that the java 1.6 home path is put in the beginning of Windows path, because the first met path is used. If you have done that try to start the command prompt NOT as an administrator and check the java version. Strangely I had the same issue and I succeeded to start the java 1.6 version only in a command prompt without administrative privileges.

在PATH开头的PATH变量中添加JavaPath \\ bin。
