I have Sonar X2 Studio installed from the download, and when I first installed it, I didn't install the instruments because I do my music production in FL Studio, but I'd like to try out the instruments now. The only way I can see to do it, is to go through the actual installation process again (which means extracting the .bins from the download files). Control Panel only seems to allow uninstallation rather than modify, and I don't know if running the full installation to re-choose my components will wipe-out or overwrite any settings, templates etc. And it will be handy to know in case I decide to uninstall the instruments again later. Any advice on this?

Run the installation disk and deselect everything, then just select the few things you want to install.  It will install these items without affecting the stuff that is already installed.

Start by selecting the "Advanced install" option. The "Advanced Install" will present the component list to install.

Thanks for the replies, guys. So it sounds like going back through the advanced installation is the only option. Thanks for the tip, Kev.
