[Bug]Cannot open folder using third-party file explorer

[ZzzzzzzSkyward]

I use OneCommander as a substitute for Windows' explorer but Everything Toolbar cannot open neither OneCommander nor Explorer when I click folders in search result.
OneCommander is configured to handle any folder-opening behavior, by Explorer and Everything and other applications.

Which version of EverythingToolbar are you using?

I can't reproduce the problem. I installed OneCommander, set it as the default file explorer and EverythingToolbar opens folders correctly in OneCommander. This is what my registry looks like for that (as a result of enabling the default file explorer checkbox in OneCommander):

Also the command should be selected for Directories like this:

Could you please double check those registry entries and let me know if they match mine?

I have recently installed v1.0.3, and my registry entries are the same as yours. But in my opinion these two entries only stand for an "Open In OneCommander" entry in the menu, while what I mean is the default "Open" action. "Open In OneCommander" just works as intended.
It is more likely that Everything Toolbar did not respond to my clicking.

Seems that there is something wrong with my registry entry HKEY_CLASSES_ROOT\Folder\shell\OpenInOneCommander, I deleted it and the issue is solved.
Thank you for pointing out that this is registry-related.
