Java Verify failure unable to Configure Java Control Panel does not open ( Fix : )
this is a regular ( windows 7 bug related ) problem after successful installation of Java ( jre ) and fresh installation of Windows7 64bit or 32bit on my laptop or desktop. what worked perfectly for me was setting COMPATIBILITYMODE=WINDOWSNT to make windows launch the JP2LAUNCHER.EXE and JAVAW.EXE files properly.
jp2launcher.exe windowsNT compatibilty solves Java Verify failure problem at https://www.java.com/en/download/in...
javaw.exe windowsNT compatibilty solves unable to open or Configure Java Control Panel problem.

* search for JAVAW.EXE inside c:\program files\java\....\bin
or c:\program files(x86)\java\.....\bin\
* right-click mouse on JAVAW application icon logo
* click PROPERTIES
* click COMPATIBILITY
* tick the checkbox at COMPATIBILITY MODE
* choose WINDOWS NT service pack
* click APPLY or click OK
Now, the Configure Java Control Panel will start opening and working.


* search for JP2LAUNCHER.EXE inside c:\program files\java\....\bin
or c:\program files(x86)\java\.....\bin\
* right-click mouse on JP2LAUNCHER
* click PROPERTIES
* click COMPATIBILITY
* tick the checkbox at COMPATIBILITY MODE
* choose WINDOWS NT service pack
* click APPLY or click OK
Now, the Verify Java will be successful at https://www.java.com/en/download/in...


if we find 2 or 3 versions of JP2LAUNCHER and JAVAW when we search, then we must repeat the above for all of them.


in the Configure Java Control Panel Advanced tab we can set "Do not check" certificate revocation and disable security verification. and in the Security tab we may Edit Site List... for the Exception Site List ( add URLs to unblock sites )

Thanks for your contribution, though I have to say I've never had any Java installation or running problems on either 32-bit or 64-bit Windows 7 so I don't see how it can be a Windows 7 bug.

Or, if it is a bug, you haven't installed the fix from Microsoft whereas I and most other Windows 7 users probably have.
