In the past, I have used the mailR package with no issues on both Mac and Windows. Ever since the last R/RStudio update, mailR and rJava will no longer work. I can install both packages just fine. But, I cannot load them with the library() command. When I try, I get the following errors:
> library(mailR)
>Error: package or namespace load failed for ‘mailR’: .onLoad failed in
loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)

From what I have found just Googling around, it seems that I need to manually change a file path in one of the functions. I think I can find my way around the Java folders to get what I need but I'm not sure how to manually change a file path in a package like this.
I think I have all the pieces to fix this problem, I just need a little guidance on orchestrating my solution. Thanks!

I have tried to call the library xlsx, since I want to save data in multiple-sheets excel files, but I got a Java-related error. Even when I run library(rJava) I have this error code:
Error: package or namespace load failed for ‘rJava’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/me/Documents/R/win-library/4.0/rJava/libs/x64/rJava.dll':
LoadLibrary failure: The specified module could not be found.
The solutions I have found online are quite old and none helped to solve the issue: I have tried to reinstall Java 64 bit on my OS (Windows 10-64bit), and the package rJava, I have tried to set Java home with Sys.setenv(JAVA_HOME="C:\Program Files\Java\jre1.8.0_271\") without success. I use R 64 bit.
Do you have any suggestions?
Finally, the solution reported here worked for me. The most important thing is to download the offline version of Java

I have not seen this specific error in any threads here on in this community. Though I do believe the issue to be related to some other threads.
I have downloaded 64-bit java, and have tried to fix the path to java with:
Sys.setenv(JAVA_HOME='C:\Program Files\\Java\\jre1.8.0_65\\bin\\client\\jvm.dll')
