Cant download package xlsx or rjava R

I am trying to download the xlsx package in R but get the following error message:
Error: package or namespace load failed for 'xlsx':
.onLoad failed in loadNamespace() for 'rJava', details:
call: fun(libname, pkgname)
error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.

I have also tried to download rjava, but get this error message:
ERROR*> JavaSoft\{JRE|JDK} can't open registry keys.
ERROR: cannot find Java Development Kit.
Please set JAVA_HOME to specify its location manually

I have reinstalled Java to my computer, with the same architecture s my computer and R (64-bit), which most of the help online says that I should try out. Have anyone experienced the same problem?

R version 3.5.2 (2018-12-20)
Platform: x86_64-w64-mingw32/x64 (64-bit)

Java version on my CPU: java 10.0.2 64 bit
I try to use the qdap package which also needs rJava and this works just fine.

Error : package 'rJava' could not be loaded
This package is not loaded because JAVA_HOME is not set.
It can be done by first installing depending on your R (32 bit or 64 bit), Java 32 bit or 64 bit.
Download java from here: https://www.java.com/en/download/
Using this find JAVA_HOME address:
find.java <- function() {
for (root in c("HLM", "HCU")) for (key in c("Software\\JavaSoft\\Java Runtime Environment",
"Software\\JavaSoft\\Java Development Kit")) {
hive <- try(utils::readRegistry(key, root, 2),
silent = TRUE)
if (!inherits(hive, "try-error"))
return(hive)
}
hive
}
Load find.java and you will find the address for JAVA_HOME. Enter that address here:
Sys.setenv(JAVA_HOME='C:\\Your\\Java\\Directory')
library(rJava)
That should load the package rJava.
ERROR: loading failed for 'i386'
This error is maybe because you have downloaded both version of R (32 bit and 64 bit) and devtools tries to build for both of them.
You can use this:
devtools::install_github("mne-tools/mne-r", INSTALL_opts=c("--no-multiarch"))
I was also getting the similar type of error and after searching through I came across this solutions which worked for me.

LoadLibrary failure RJava

I've been trying to load the qdap package, searching on here and troubleshooting, - realised Java couldn't be found. Uninstalled and downloaded Java - assuming I've done the correct 64 bit version as I am assuming I have RStudio 64 by checking
> R.Version()
$platform
[1] "x86_64-w64-mingw32"
I'm using "R version 3.4.3 (2017-11-30)" and Windows 10
Followed the advice here and set the following
Sys.setenv(JAVA_HOME='C:\\Program Files(x86)\\Java\\jre1.8.0_181')
ran this
find.java <- function() {
for (root in c("HLM", "HCU")) for (key in c("Software\\JavaSoft\\Java
Runtime Environment",
"Software\\JavaSoft\\Java
Development Kit")) {
hive <- try(utils::readRegistry(key, root, 2),
silent = TRUE)
if (!inherits(hive, "try-error"))
return(hive)
}
hive
}
Got this
find.java()
> find.java()
$`Security Baseline`
$`Security Baseline`$`1.4.2`
[1] "1.4.2_99"
$`Security Baseline`$`1.5.0`

$`Security Baseline`$`1.6.0`

$`Security Baseline`$`1.7.0`
[1] "1.7.0_191"
$`Security Baseline`$`1.8.0`
[1] "1.8.0_181"
Assumed this means Java can now be found. Also did this to check.
> system("java -version")
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) Client VM (build 25.181-b13, mixed mode, sharing)
So try to load rJava again.

I've tried to follow the advice given in here and as shown above I know I have Java and a Java Run Time Environment and I have followed some of the suggested fixes already. I haven't done the PATH fixes as I'm not sure what exactly my PATH is, if it's wrong and how to change the PATH or put server in path. I've got as far as this but not sure how to decipher it.
> Sys.getenv("Path")[1] "C:\\Rtools\\bin;C:\\Program Files\\R\\R-3.4.3\\bin\\x64;C:\\Program Files (x86)\\Common Files\\Oracle\\Java\\javapath;C:\\Program Files (x86)\\Intel\\iCLS Client\\;C:\\Program Files\\Intel\\iCLS Client\\;C:\\WINDOWS\\system32;C:\\WINDOWS;C:\\WINDOWS\\System32\\Wbem;C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\;C:\\Program Files (x86)\\Intel\\Intel(R) Management Engine Components\\DAL;C:\\Program Files\\Intel\\Intel(R) Management Engine Components\\DAL;C:\\Program Files (x86)\\Intel\\Intel(R) Management Engine Components\\IPT;C:\\Program Files\\Intel\\Intel(R) Management Engine Components\\IPT;C:\\WINDOWS\\System32\\OpenSSH\\;C:\\Program Files\\Intel\\WiFi\\bin\\;C:\\Program Files\\Common Files\\Intel\\WirelessCommon\\;C:\\Users\\grant\\AppData\\Local\\Microsoft\\WindowsApps;"
I've also tried downloading and using Dependency Walker and didn't understand it.
Have I made an error in my assumptions? Is there an issue with my Path and if so how does Path get changed? Or is there anything else I can try?

JavaVM Failed to load

I'm trying to load the "openNLP" library in RStudio and I'm getting the following error. I get a similar error when I try to install the "RWeka" package.
How do I troubleshoot this?
library(openNLP)
Error : .onLoad failed in loadNamespace() for 'openNLPdata', details:
call: .jinit()
error: JNI_GetCreatedJavaVMs returned -1
Error: package or namespace load failed for ‘openNLP’
JavaVM: requested Java version ((null)) not available. Using Java at "" instead.
JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.

Found a solution to my issue. This is what worked for me. Please see below:
Launch R at the command line (to test the solution):
sudo R CMD javareconf
export LD_LIBRARY_PATH=$JAVA_LD_LIBRARY_PATH
LD_LIBRARY_PATH=$(/usr/libexec/java_home)/jre/lib/server: open -a RStudio
Now within RStudio:
install.packages("rJava", type = "source")
install.packages("openNLP")
require(rJava)
require(openNLP)
To launch RStudio from finder (El Capitan), you have to link libjvm.dylib to /usr/lib.
sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
