Trouble configuring RStudio to use repos from RSPM

From my experience (see my comment in the other thread linked below), one more step is still needed to get QuickStart IDE to install packages from QuickStart RSPM: Uncheck the "Use secure download method" box. If you don't do this, access/installation will fail because IDE will require that the repo URL be https, and the localhosted QuickStart RSPM does not offer that.
