dll files into InnoSetup

building my app at 64-bit I found in the build-folder six .dll files.
I would like to know:

  1. should all of them be included into the Innosetup script, or is XojoGUIFramework64.dll enough?
  2. how to include them? i.e. should “Flags: ignoreversion” be added? or not added as below?

Source: “mySourceFolder\x64\*”; DestDir: “{app}”; Flags: ignoreversion recursesubdirs createallsubdirs
Source: “mySourceFolder\XojoGUIFramework64.dll”; DestDir: “{app}”;

Thank you.
