          @Guido-Thelen ,

          I just ran a couple quick experiments (downloaded the released versions of your plugins using plugins admin):

          it loads fine in either, and gives
          5e5abb0e-86ec-4669-a20c-3c4609b46e02-image.png

          If I copy over the 32bit DLL and put it in the folder for the 64bit Notepad++, NPP gives me the error:
          23948216-5bd5-4c62-be09-0f5ae2139a2a-image.png

          That’s similar, but is explicit about the 32-bit nature of the plugin DLL. I think “Failed to load” is indicating something different – a bug in your source code for the plugin, probably.

          You said you did a lot of refactoring, so you probably got something wrong during the refactoring.

          It might be a good idea for you to try to recompile the 5.3.35 version of your code in your existing setup, and make sure that you can still compile it properly and get it to work. Then compare VS settings between the two, to make sure that there isn’t some missing external resource or option difference.

          I know that sometimes you cannot avoid doing “major refactoring” when adding a new feature or changing libraries you depend on. But when at all possible in my software development, I try to make incremental changes and tests, and make sure everything still works at various stages along the way, because that helps prevent issues like this.

              @PeterJones I removed some of my changes. It is still not starting but I am getting a more clear error message.
              “This ANSI plugin is not compatible with your Unicode Notepad++”
              It looks like I am missing the point where I turn my Plugin into an UTF-8 plugin.

              Any idea where I can find this switch?

                  this error happens when isUnicode function is not exported.
                  isUnicode should always return True.

                    @Ekopalypse ok. I checked the UnmanagedExports class and it contains isUnicode function (see code snippet above)

                      but is it really exported??
                      Tools like dumpbin /exports can show if the function is really exported.

                          indeed. this could be the problem. When I build the same solution with VS2015 instead of VS2019, it works (without changing anything). Probably the Export is not done in VS2019.

                            last time I played with C# plugin interface there was an
                            extra export step at the end. I can’t remember its name.
                            Maybe in 2019 it does have to be called slightly different!?

                                  @Ekopalypse ok. found it. it is strange. the version built with VS2015 does not have the isUniCode function exported, but it works

                                    that is strange, indeed. How can npp access non-existent function pointers??
                                    Let me check this again.

                                            the version built with VS2015 does not have the isUniCode function exported, but it works

                                            Just in case: have not you forgot about the “/exports” parameter of dumpbin?
