Unable to connect to SAP using 64bit dlls, whereas it works with 32bit C#

Hi Team,

I facing a issue when using the 64bit versions of icudt50.dll, icuin50.dll, icuuc50.dll in my code.
This fails with the error pop-up message as, "above dlls path needs to be added to PATH variable". I have added them, but still it fails. I have added them as part of project reference as well.

Whereas, the 32bit of these dlls are working fine.

Here is a screenshot for the same

if we echo PATH, we can see that these dlls are added there

I tried to restart, add path again and again, deleted these dlls and added them one more time but still getting the same error.

Can anyone help me out here?
