Since you are using an old R version, the ipred package requires compilation to be updated, and for that, you need to have RTools installed in your system.

You can download a suitable version of RTools from here

Although, I would recommend updating to the latest R version (4.1.2) so you can get access to precompiled binaries

Thank you so much. It is working perfectly now, I updated to the newest R version as suggested.
