I have just replaced the pc on my mill (previously running mach3 for many years on windows 7 without problem until pc failed) with a new windows 11 computer with  a fresh installation of mach 4 v4.20 4809 using ESS.

The mill is all working but when
I try to edit the m6macro I get the error loading machipc  from file mach4hobby\modules/machipc.dll.  (the file is there)

I also tried V4.20 5036 but it gives the same error.

I then  installed the same versions on a windows 10 machine and the editor works fine which makes me think windows 11 is the problem but others are using it.

Does anyone have any ideas what could be the problem?

yeah.. I have a pretty good idea.. MICROSOFT WINDOWS 11!!! its really good if you want to do phone apps.. texting.. reading emails.. going to buy something on Amazon.. not much good at anything else.

I would try installing the Visual C/C++ runtime as Administrator for Visual Studio 2017.
