I don't remember you get an option to not install the standalone applications during the install process. But you can choose which plugins to install, as you can tick off those you don't wan't to install.
Did you get the option not to install the standalone versions, or did you just delete the path?
If you have'nt installed the standalone applications, then perhaps that have caused your issue, if i remember correct that you don't get the option not to install them. I can't tell for sure though.
