Hi. Few weeks ago i download Witcher 3 (76 hours downloading O.o) and today i had to reinstal my windows.
After that galaxy client doesn't work so i reinstall it too. here is my question. i make save copy my witcher 3 folder just in case and how can i add it to galaxy client without downloading it? "import folder" in properties dont working i copy witcher 3 folder to "Games" folder in "galaxy client" folder but still not working.

what can i do?

p.s
sorry for my english :D

more -> manage installation -> import folder and head to the folder with The Witcher.
If that doesn't work, try reinstalling Galaxy.
