View File is broken in MC x64 v 16.0 (build 3166)

[Anti-Bacterial]

Today I updated to Multi Commander (x64) v 16.0 (build 3166).  Build date May 29 2026.
Problem: The View File menu (and F1 key) is no longer working for txt, csv files. When I select a txt file and choose View File, nothing happens. However it does work correctly for PNG files. I have not testing other file formats.  Any suggestions please? Thank you

This is beta version. so please keep it to the beta forum.. (I moved post)

Yes a file is missing for Windows 10, on Win11 this file is already installed by the system.


Unpack and place the included file next to MultiFileViewer.dll, for example in C:\Program Files\MultiCommander (x64)\Extensions\MultiFileViewer\
But it depends on install folder.

Thanks Mathias, it's working properly now —the internal-text-viewer is firing up once again ! Also, I will test further and see if I encounter any problems with MC progress dialog box hanging again when moving files to USB drives. The file I moved was a 1 MB SNES ROM (.SFC) (just some game file.) Had no issues when moving via TeraCopy however. 😎👍
