I seem to have exactly the same issue as Guga had in this question.
I was receiving the same message "invalid Directory." But in this case, I have removed all spaces from the path name. I have no problem changing my working directory to this but I cannot apply the actual path.
I successfully change directory with:
cd ~/Gamestuff/PlayOnLinux/LeagueOfLegends/drive_c/RiotGames/Leagueoflegends/
But when I try:
mono tuxlol.exe patch --dir ~/Gamestuff/PlayOnLinux/LeagueOfLegends/drive_c/RiotGames/Leagueoflegends/
I get
"The specified directory is invalid."
What could I be doing wrong? The answers to his question fixed the space issue, but I have none. I hate asking a separate question, but I've been stuck on this single issue for over an hour.
Thanks!
