Dear All

I am grateful to you for your response to my queries related to maxent. I
succeeded to install rJava in 32bit R (not able to install in 64bit R).
Still maxent jar file is not executing.
My operating system is 64 bit.
Kindly advise what necessary corrections I should take keeping my 64 bit
operating system intact.
Shall I install 32 bit Java for 32bit R with operating system 64bit.
I would try but what are technical problems I do not know.
I have various options available to me by using 32bit computers of my lab
also. Each time I fail to execute maxent jar file.
I would appreciate your kind response.

Thanking you

With best Regards
