Problem in making atari game environment in window 7 (missing MSVCP140D.dll system error)

[Ali-Ai]

I tested on Win 10 it was Okay. However, on Win 7 the error pops up.

Thanks for filing the issue! This was moved from openai/gym#1592

We don't officially support windows, but a PR that fixes this issue would be cool to see. Likely the DLL should be included in the Python wheel somehow.

Hi @Ali-Ai and @christopherhesse , the same problem happens to me.

Requiring msvcp140d.dll indicates that the compiled ale_c.dll is the debug version instead of the release version, which is not appropriate to be distributed to pypi.

Note that installing msvc++ redistributable won't help, as it only provides msvcp140.dll, not msvcp140d.dll. The only solution I guess is installing the full vs2017 that contains the vc++ sdk.

As I am not familiar with cmake, I also have no idea how the CMakeLists.txt should be modified to compile the release version instead of the debug version. Maybe this post will help.

Hope someone could fix it.

Hi,

This should now be fixed when atari-py gets merged into the ALE. We now build using --config Release on deployment: https://github.com/mgbellemare/Arcade-Learning-Environment/pull/272/files#diff-2eeaed663bd0d25b7e608891384b7298R49
