I made a costum sensor panel and wanted to try it out so I wanted to install RTSS but when I try to install it, it aborts the installaion because "rtss is currently active". I don't know what to do now. I close eveything I can think of, rebooted the pc but still the same issue. I've read that I should close all applications that are hooked with rtss but I can't think of any apps to close now xD Hope someone can help ^^
