I have a UPlay SH4, but with my Steam SH5 in the same folder, and UPlay automatically picked-up my SH5 Steam install, and offered to put it there when I did the inital SH4 Gold install when this Win10 laptop was purchased. I have everything in the "C:\Ubisoft \Ubisoft Game Launcher" folder, which I made during the install, and had deleted the "Program Files (x86)\" portion from the path. I have had no ill effects from UPlay (as of yet), and I just did a "test" re-install yesterday. As soon as I did my first SH5 start after the re-install, the game did its "update" check, and UPlay downloaded its "update" (from September of this year). Afterwards, I did a TWoS install / activation, and everything went as expected. I would suspect install "path" issues myself also. May-haps if the Launcher or the game is in Program Files, it then "helps" the player by "tagging" the SH5.exe file??...
