Hello AlKoppen,
Unfortunately IE has reached it's end of life as product, and many security and functional concerns are present for users still using it. This is why in newer versions of Windows 10 has been even completely removed from usage.
You can try enabling the compatibility mode for IE in Edge, following the next article: https://techcommunity.microsoft.com/t5/enterprise/manual-how-to-set-up-ie-mode-internet-explorer-integration-in/m-p/774900
But in case the program requires specific libraries from IE (maybe even earlier versions than IE11 - which would be completely obsolete at this point) there would be no other solution than using a legacy operating system such as Windows 7.
