Error occurred during initialization of VM. I could not find agent library jvmhook on the library path, with error: %1 is not a valid Win32 application.

Solution you can get here in this link


http://sqa.stackexchange.com/questions/5183/error-upon-starting-select-server-could-not-find-agent-library-jvmhook

Java was started but returned exit code=1

For this we have to go to Command line

type

c:\> java -version
then you can find some error like
Error occurred during initialization of VM. I could not find agent library jvmhook on the library path, with error: %1 is not a valid Win32 application.

So now you have go to Control panel-> System -> Environment variables

Under "System Variable" tab you can find
JAVA_TOOL_OPTIONS

Delete that one and click on ok

Now again go to c:\> java -version

Now it will work fine.

Your eclipse problem also will resolve.
