Same is happening to me, too. I have searched through this thread and this happens occasionally with nobody really knowing an answer. Maybe a few screenshots of the files in the root could be helpful? CHanged the name of the root directory of this game to "test" because somewhere suggested weird characters in the directory name could be the culprit.
Open UnRen.bat in an editor and locate:
'
REM --------------------------------------------------------------------------------
REM Set our paths, and make sure we can find python exe
REM --------------------------------------------------------------------------------
set "currentdir=%~dp0%"
set "pythondir=%currentdir%..\lib\
windows-i686\"
set "renpydir=%currentdir%..\renpy\"
set "gamedir=%currentdir%"
if exist "game" if exist "lib" if exist "renpy" (
set "pythondir=%currentdir%lib\
windows-i686\"
set "renpydir=%currentdir%renpy\"
set "gamedir=%currentdir%game\"
)
if not exist "%pythondir%python.exe" (
set "pythondir=%currentdir%..\lib\
windows-x86_64\"
set "renpydir=%currentdir%..\renpy\"
set "gamedir=%currentdir%"
if exist "game" if exist "lib" if exist "renpy" (
set "pythondir=%currentdir%lib\
windows-x86_64\"
set "renpydir=%currentdir%renpy\"
set "gamedir=%currentdir%game\"
Then put py2- in front of the
bolded text above (in the editor, ofc). So e.g
set "pythondir=%currentdir%..\lib\
windows-i686\"
becomes
set "pythondir=%currentdir%..\lib\py2-
windows-i686\"
and so on for all 4 lines.
