After applying the recommended changes to the setup files (listed here), I successfully installed Scrypt on Python 3.5. But I can't figure out how to actually get it to run or to pass its own tests. It complains that "_scrypt" doesn't exist but, per the scrypt directory, it does. My attempt:

Any suggestions would be greatly appreciated. Edit: The error occurs regardless of where the 'python' command is run.
After using Process Monitor to track the activity of Scrypt on my working desktop and my non-working laptop, I discovered that it wanted OpenSSL's libeay32.dll. In the beginning, I had chosen to install its DLLs in the /bin directory but, unfortunately, Scrypt doesn't check there. After reinstalling OpenSSL and choosing to install those in the Windows directory, it ran just fine. Scrypt is in need of a serious update.
