          I start to remember that I read some conversation about
          security concerns regarding sideloading dlls.

            @Ekopalypse so, I’ve tested my minimal plugin build in 7.8 with python37.dll inside plugin dir and it works.

            My question from the top of the thread has been solved.

            Thank you very much!

            ps

            I still need to check if my main plugin will be working…
            Struggling to upgrade third-party libs and other dependencies…

                @Ekopalypse you are doing great job , thank you !

                ps
                I came across a next roadblock , that’s more a pywin32 issue.

                See https://github.com/mhammond/pywin32/issues/1658

                May be you would have a hint how to troubleshoot that. as that seems to be sort of related to dependency lookup process.

                In a nutshell I’ve NPP plugin linked against boost::python which loads at startup some initialization python code. And it’s was working fine under py 3.7 and npp 7.7.

                Finally ( with your help) I managed to upgrade npp from 7.7 to 7.9
                and partially from winpython 3.7 to winpython 3.8.

                My NPP python plugin is loaded at startup, but execution of initialsation python scripts fails to import win32api.
                Embedded python wrapper is working fine ( I guess ) as import os / import sys and other simple code is working inside my plugin.

                I’m using win py 3.8 and latest pywin32 ( 300)

                  @Stier-Hahn pywin32 is installed sort of correctly as it works from python command line.

                    @Stier-Hahn

                    there is an additional
                    ...\AppData\Roaming\Python\Python38\site-packages
                    path when used by the command line.
                    Maybe give it a try to add it to your sys.path from embedded python.

                    Do you know procmon ?
                    It could be used to see what npp and your plugin tries to load with a filter set to path contains whatever

                    48b96c60-c947-48f4-9987-af19cf359c3d-image.png

                    If importing pywin32 failed with unable to load dll
                    then one of those
                    2f2d6355-c2f6-4c2c-b92d-c49ef97d7714-image.png
                    can not be found I guess.
                    python38 shouldn’t be the problem but pywintypes38.dll might be in this additional path I’ve mentioned earlier??

                      @Ekopalypse cool, thanks for advice, turned out to be pywin32_system32 not being searched for some reason

                      Untitled.png
                      Apparently lookup path was (intentionally screwed up) modified

                      I managed to fix my problem by placing pywintypes38.dll and pythoncom38.dll to NPP root
