Like i told you in the email, find out whether or not your radeon has shader module 2.0, aka sm2.0. Hdrish cannot be used on cards that have a shader module less than 2.0. The radeon 9550 appears to be sm2.0 compliant, so that means you can use the more advanced smartshaders like hdrish.
But, to use the smartshaders, open psscontrol2.exe first. Then click the browse button to search for smartshaders to load. The smartshaders can be located wherever you want, so it doesn't matter on their location, it just matters that you can navigate to them with psscontrol2.exe to load them. Once you've browsed for the desired smartshader click open after done browsing and selecting the smartshader file of your choice. Then after that, the smartshader is loaded, you can even close psscontrol2.exe and the smartshader will still be loaded. That smartshader goes away only if you go back into psscontrol2.exe and click turn off smartshader.
And there you have it. Like psscontrol2.exe says, "there is no guarantee if this will work with future or current graphics drivers", so this may actually be a factor where you'd have to get a past version of drivers, but i doubt that.
