First let me say that I'm still using LR6 as a stand alone install. I've had it installed on the Window 10 driven laptop that is my general purpose machine since purchasing the machine. This is not my primary editing machine so historically I have not had any additional PP software on it. A couple of days ago I decided to install DxO PL4 and Topaz AI Denoise and AI Sharpen. All three of those have LR plug ins. After doing so when I opened LR all preferences/options were reset to default settings. I mean ALL. It was like a new install of LR other than I did not have to re-enter the key code. Anyone had similar experience?
