Electron compatibility? Error: %1 is not a valid Win32 application.

[deed02392]

I can't seem to get the module to run.

node.exe is 64 bit, OpenSSL win64 was installed (from slpro) and x509 builds against the lib there no problem. However when it come to running, I get this error:

Error: %1 is not a valid Win32 application.
