We have an older 16-bit app which we need to run on WinXP. If I run the
app from a shortcut in the start menu (which points to the file on the
server) it runs fine. If I run the app from the NAL, which points to the
same file on the server, it doesn't work.

I looked up the error and traced it back to an issue with wowexec.exe,
which is a windows system file.

There's some sort of compatibility issue that Zen is not able to handle.
Is there anything I can do?
