Could not load qgis_app.dll

I have run successfully QGIS version 3.2.1 (Bonn) in my old laptop (Windows Vista).
Then I installed the desktop version 3.4.2 (Madeira), but it will not start.
The error message is: "Could not load qgis_app.dll".
I have compared the files (qgis.bat, o4w.env and qgis-bin.env) between both versions and cannot find any difference or reason for the failure.
I will append those files.

I apologize, that I am not any specialist in such software troubles.
May the reason be, that those versions cannot be simultaneously in my laptop?

Best Regards,
