the above steps make plugin work fine ie8 on windows 7.

i followed same steps did ie8.

i'm not sure went wrong, please 1 me resolve issue.

is there security related restrictions microsoft on ie10 on win8 , 8.1?

as same plugin works fine on ie11 , ie10 on windows 7 , , not working on ie 10 comes windows 8 , 8.1 os.

i have bad news you: you're working technology obsolete. activex support being removed microsoft's browsers.

windows 8 , ie10 started process of deprecating activex technology in browser. activex has been constant source of major security issues ie, , improvements in built-in browser capabilities in recent years, becoming less , less useful. microsoft have started removing activex support browsers.

in ie10 , ie11 under windows 8 partially disabled -- in full standards mode, small number of known , trusted controls supported; others blocked. in compatibility mode, still possible run activex controls before, lose of more modern browser features.

in microsoft's latest browser, edge (the replacement ie comes windows 10) don't have option of compatibility mode: activex support removed.

so short-term answer here if want run activex controls in ie10 , ie11, need set browser compatibility mode.

but longer-term answer you're going have switch away activex technology browser controls, , switch html5 , javascript.
