DOpus 10 not replacing Explorer

Help & Support
1

Due to a file system error, my tech had to reinstall Win 10. DOpus had to be reinstalled, but it has not replaced Win Explorer as it used to. The only way to access DOpus is directly from its icon or the taskbar. I noticed that DOpus disappeared from the boot menu also.

Any help?

Is Explorer Replacement turned on in Preferences?

Note that Opus 10 predates Windows 10 by several years, so it may not know how to hook Explorer perfectly for that version and was never fully supported on Win10 like Opus 12 is.
