Well, I did not notice EmEditor’s Find in Files Explorer context menu until you told me in this post, because I used to install 32-bit EmEditor on a Windows 7 x64 machine, in order for some 32-bit plug-ins to work.
You know, current(v11.0.2) 32-bit installer will not install context menu on 64-bit Explorer.
So, I highly suggest your 32-bit installer can add context menu to a 64-bit Explorer. In case that is not easy to do, I hope you present a way to manually add that context menu.
