Issue #83 and #167 does not solve the problem.

OSError: [WinError 193] %1 is not a valid Win32 application

Process finished with exit code 1

I'm using Pycharm IDE on Win10, mujoco-py 0.5 and the error is the same with Python 2.7 and 3.5.2 interpreters.

Libraries: .mujoco/mjpro131 and here is my mjkey licence aswell.

To me seems like it can not load the mjlib library.

Encounter the same problem.

Fixed by editing some files manually:

mjlib.py
from

line 14
elif sys.platform.startswith("win"):
    libfile = os.path.join(path_prefix, "bin/mujoco131.lib")

to

elif sys.platform.startswith("win"):
    libfile = os.path.join(path_prefix, "bin/mujoco131.dll")

platname_targdir.py

line 6
elif sys.platform.startswith("win"):
    platname = "win"
