I am using PSP8.1. I have many plugins in a folder c:\plugins\ in sub folders under their own name. These all work.
I have installed harrysfilters3 from the exe file into that folder, found that they were not in a subfolder of their own, made a subbfolder "harrysfilters3" and moved them into that. When I open the effects menu and the plugin filters submenu, harrysfilters3 does not appear.
They did not appear before I made the subfolder, and I thought that was the fault.
What to do ? Help please.
