I suggest to implement the following feature:
The Redistribution Folder of the L&L Installation should also contain a 64 Bit Version of llviewxx.exe
A typical use case might be:
If you redistribute List & Label only as a 64-bit application and integrate the standalone Viewer in your package, you need 6 additional 32-bit DLLs and 2 LNG files that a 64-bit viewer won’t need.
