R on Windows 10, rcmdr 'hasjava' error

Question

I am trying to run biodiversity r in r studio with the biodiversity rgui which links up to the rcmdr. I have tried every help forum to find an answer but come up with nothing. I reinstalled R, R studio, updated all packages, installed rjava and javagd and still it refuses to work. I am at wits end!!! I cannot find anything about 'hasjava' and I have updated and installed java already.

Below is copy pasted from the console.

Restarting R session...

> library("BiodiversityR", lib.loc="~/R/win-library/3.2")
Loading required package: tcltk
Loading required package: vegan
Loading required package: permute
Loading required package: lattice
This is vegan 2.3-0
BiodiversityR 2.5-3: use function 'BiodiversityRGUI()' to launch the BiodiversityR Graphical User Interface

> library("rJava", lib.loc="~/R/win-library/3.2")

  error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.

Tried everything on the post, nothing helps, I am running on windows, I think that is the problem. Have 72 hours to figure out a solution or simply not publish what should be awesome results. Anyone to help??? Please ASAP — Charmaine Crystal Drury, Sep 17 '15 at 12:29
Have you tried installing [Java](http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html)? Have you ever got this to run before? What does `system("java -version")` give you? There are a few things you could add to what you've tried. — sebastian-c, Sep 17 '15 at 14:42

This problem has nothing directly to do with Windows or with Java.

The Rcmdr package no longer uses Java, and the function hasJava(), which was defined in and exported by the Rcmdr, no longer exists. Apparently BioDiversityR uses this function and needs to be updated appropriately.

You might report your problem directly to the maintainer of BioDiversityR.

I hope this help, John
