I installed Ghostscript and edited the path in the environment variables, moving the GS lines up to the middle of the list.
Now, EPS files show up to import but when I select and click import, I get the error message: Failed to load requested file

I found directions to run Ghostscript from the command line prompt and I can convert EPS files to PDF that way. When I open the PDF, it imports with no issues. So now we know Ghostscript is working properly. Even though it is now possible for me to open an EPS, it's not really practical to keep doing it this way. Also, I can't find the site again with the command prompt instructions.
This seems to narrow down the problem to the interface between Inkscape and Ghostscript?
Any help getting this to function is appreciated.
My system: Windows 10 64-bit running Inkscape v. 0.92.3 64-bit for Windows
