Explorer Replacement on Windows 10

The explorer replacement option doesn't seem to be working on my installation of windows 10, whenever I select something akin to "Show in file manager" on either my desktop or in my internet browser, nothing happens. No windows explorer and no Directory Opus.

Windows 10 Pro, 64-bit

Any help is appreciated.

If you turn off Explorer Replacement, do the same menu items then work to open File Explorer?

Try then turning it back on. Is it still not working?

Note that launching the whole dopus.exe process elevated can break Explorer Replacement.

I removed "Run as Administrator" and that seems to have done it, thanks!
