I'm receiving an error message on the R software stating, "MCR is not installed."

I'm a complete beginner at programming, so please excuse any mistakes or lack of knowledge on my part.

I want to use a package in R that requires the MATLAB Compiler Runtime (MCR).

Despite installing the specified version and verifying the environmental variables, among other things, I keep encountering the error message shown in the image below.

When I click 'OK', R displays an error message that reads " Error in BNL. For details, use the control option, show=TRUE　".

Additionally, even when I specify show=TRUE in the control options, there is no change in the error message mentioned above.

I might be facing a very simple problem, but I'm struggling to solve it. I apologize for the inconvenience, but if anyone knowledgeable can provide any insights, I would be very grateful.

(MCR 8.3 corresponds to MATLAB R2014a)

I wonder if the difficulty has to do with 32 bit versus 64 bit?

Thank you very much for viewing my question and for your comments.

My PC is 64-bit, so I initially chose the 64-bit package that was provided and installed the 64-bit MCR. I had tried the 32-bit version as well, but neither seemed to work.

However, after reading your comment, I decided to install the 32-bit MCR and the 32-bit package. To my surprise, it worked without any errors, and I was able to get the correct results!!

I had tried everything within my understanding and was really at a loss, so your assistance was incredibly helpful.Thank you for taking the time to respond during the New Year holiday period. I hope your year is filled with good things.
