Hi, I want to speed up my computer, so i remove unnecessary applications. However, i see that there are two MATLAB Compiler Runtimes which are MATLAB Compiler Runtime 8.2 (32-bit), and MATLAB Compiler Runtime 7.17. I think my computer doesn't need both. Therefore, i wonder if i should remove 8.2 (32-bit) because my computer is 64 bit ? Thanks!

You have to think about the computer(s) to which you intend to deploy the compiled applications. Are they also always going to be 64-bit? If you plan to deploy to a 32-bit computer, you will need the 32-bit compiler and MCR.

There is a one-to-one relationship between MCR version and Matlab versions so if you have executables compiled from a given version of Matlab you will need the MCR from that version to be able to run them.

If you have no executables from the version of Matlab associated with an MCR then you can delete it and it has no effect on any other MCR versions or executables from different Matlab versions.
