All you really have to do is to edit the 'target' line in the provided 'java64' short cut (in the validator's directory) by right clicking the shortcut and choosing 'properties':

D:\Programs\Java7\bin\javaw.exe -cp classes checkEDB.EDBValidator

In other words: do a search were your javaw.exe file is and then update the path to it.

Note: the short cut has to stay to in that directory, if desired elsewhere make a shortcut from this shortcut.
