Can't load rggobi.dll though it appears to be available

Question

I'm trying to use clusterfly which depends on rggobi.

I load clusterfly and receive this error:

> pacman::p_load(caret, clusterfly, devtools, geonames, inTrees, mclust, party, 
+                RDSTK, reshape, ROCR, RRF, sqldf, stringi, tree, xlsx)

Failed with error:  ‘package ‘rggobi’ could not be loaded’
Warning message:

which seems to basically say that rggobi.dll is not located where it's supposed to be.

So, I try directly installing and loading rgobbi and get the same error:

> install.packages("rggobi")
trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.2/rggobi_2.1.20.zip'

package ‘rggobi’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\hackr\AppData\Local\Temp\RtmpopFKT2\downloaded_packages
> require(rggobi)
Loading required package: rggobi
Error in inDL(x, as.logical(local), as.logical(now), ...) :

  LoadLibrary failure:  The specified path is invalid.

I find this strange, so I have a look in Windows Explorer and the file rggobi.dll is right where it's supposed to be:

After another failed attempt to load it, my next thought is that there could be some sort of file permission problem. So, starting with the rggobi folder, I chmod 777 to set the maximally permissions.

I still can't load the package and I repeated the process of chmod 777 and attempting to require(gobbi) for each successive folder level and directly on rggobi.dll:

C:\Program Files\R\R-3.2.0\library>chmod 777 rggobi
C:\Program Files\R\R-3.2.0\library>cd rggobi
C:\Program Files\R\R-3.2.0\library\rggobi>ls
DESCRIPTION  LICENSE  Meta       NEWS  data  help  libs

C:\Program Files\R\R-3.2.0\library\rggobi>chmod 777 libs
C:\Program Files\R\R-3.2.0\library\rggobi>cd libs
C:\Program Files\R\R-3.2.0\library\rggobi\libs>chmod 777 x64
C:\Program Files\R\R-3.2.0\library\rggobi\libs>chmod 777 i386
C:\Program Files\R\R-3.2.0\library\rggobi\libs>cd x64
C:\Program Files\R\R-3.2.0\library\rggobi\libs\x64>ls
rggobi.dll  symbols.rds
C:\Program Files\R\R-3.2.0\library\rggobi\libs\x64>chmod 777 rggobi.dll

Finally, after opening an issue on Github, Hadley Wickham deferred to a lawremi, who suggested trying 32-bit R, but that also led to the same result.

How can I make this dll/package available to R?

My solution was to follow the instructions below from here

If you also want to install rggobi, you can install everything from within R, with the following command: source("http://www.ggobi.org/downloads/install.r")
