Topaz Studio standalone without updating Photoshop plugins?

I have the classic studio collection plugins for Photoshop. These are configured the way I like them, I want to continue using them as Photoshop plugins and I don’t want to change my workflow. I don’t care if they’re never updated again - I want to use them like they are until I can’t anymore.

However, I would like to try out Topaz Studio as a standalone application so I can check out the plugin updates directly in Topaz Studio and maybe even get AI Remix.

If I install the standalone app, is there an option for it to leave my Photoshop plugins alone or will it auto detect that I already have Topaz software installed and overwrite them?

No it won’t overwrite them and the older plugins you have will be available in Topaz Studio through the Plug-ins menu.
