Error appear when double clicking on a Hash File to check.

Hello all,

I am hoping for some help as this issue has stumped me. I have installed Teracopy on around 100+ users and I have had no issues bar 2 who every time they double click on a hash file rather than running the verification it opens an installer instead…

Now I have re-installed it, restarted etc… and I still come up with the same issue. What is causing this and how do I best resolve it?

Is their an X64 installer for tera copy?
