How to install into P/S after?

Hi, I have re-installed my Photoshop CS6 but already have Topaz Studio, Adjust AI and Denoise AI installed on my computer how please can I get these to be seen in P/S CS6 thankyou. Russ

Just run them as standalone applications and they should install themselves in the applications such as photoshop and Lightroom.

If that doesn’t work just download the installers, run them and make sure the application is run from the installer as the last step.
