Problem running PyPy3 on Windows 10 Enterprise


I'm trying to run PyPy3 on Windows 10 Enterprise (with the VC++ redistributables for 2008, 2013, and 2015). PyPy2.7 7.1.1 runs with no problems. However, both PyPy3.6 v7.1.1-beta and PyPy3.5 v7.0.0 fail with the message "The application was unable to start correctly (0xc000007b)". My web research indicates that 0xc000007b may be caused by a 32bit app trying to load a 64bit DLL, which seems possible for the 32bit Windows version of PyPy. But even if I could find the offending DLL, what can I do about it? Is there a way to tell pypy3.exe to replace a specific DLL?

Thanks in advance,

"It works for me" is not a very good answer even when it's true. Maybe you can use the tools described in How to check for DLL dependency?
