How do you progress through the Droid Explorer unpack option? I'm using a Windows 7 PC and am trying to unpack an *.ab backup file created using Helium. If I right-click on the file in Windows Explorer and select the Unpack option that now appears after installing Droid Explorer 0.9.0.4, I'm first asked for a password. I provided none when creating the backup, so I simply leave the password field blank and press OK to continue.

Then, something weird pops up, and I'm not sure how to continue. I see this window, asking me what I want to open java.exe with:



Is that supposed to pop up at this point? Am I missing something that should be installed that would avoid this? I have Java 8 Update 31 currently installed on this machine.
This looks like (as stated in my comment above) that it has to do with the Path of Java not existing in the windows PATH environment variable. 

I am adding your comment as well as part of this answer:


  Weird, that was (sort of) it! Java was in fact in my PATH environment variable, but it was using the directory C:\ProgramData\Oracle\Java\javapath\ which contains only 3 symlinks to my actual Java bin folder. Double clicking on any of the symlink shortcuts results in the window I noted above. I temporarily changed my PATH variable to point to the real Java folder, and then your Unpack feature worked fine. (I then put my PATH variable back, since I don't know what potential security issues I'd open myself up to by leaving it altered.)
