Missing DLLs error on Windows

[bananenpampe]

Even after installing the latest vesin, I have reports that vesin complains about missing DLLs:

I am afraid that I do not have exact system specs available (newer windows version, x86 processor)

FileNotFoundError: Could not find module ‘C:\Users\Len\shiftml_env\Lib\site-packages\vesin\bin\vesin.dll’ (or one of its dependencies). Try using the full path with constructor syntax.
Output is truncated. View as a scrollable element or open in a text editor. Adjust cell output settings...

Is there any way that you could provide a few instructions how this issue may be fixed (do we need to get a windows computer first to even recreate it :D )?
We tried to locally update the latest c++ redistributable https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

But that did not appear to help.

Perhaps just having instructions to build a conda environment could be helpful.

Since the windows-22 CI runner isnt complaining perhaps it depends a lot on the exact system specs, but I see Reason to believe that this may appear again, hence the idea to somehow show how it can be fixed in a virtual environment

Before we can document a fix, we'll need to understand what the issue is. Ideally this would mean having a way to reliably reproduce the error first.

Actually I might have an idea about what the issue is:

$ strings vesin.dll  | grep '.dll'
vesin.dll
MSVCP140D.dll
VCRUNTIME140D.dll
VCRUNTIME140_1D.dll
_seh_filter_dll
ucrtbased.dll
KERNEL32.dll

I recently found that we were building wheels in debug mode, which means we are linking to the debug version of most of these DLL (MSVCP140D.dll instead of MSVCP140.dll, ...). I'll try to do a new release with properly compiled code and we can then check again.

Thanks a lot for checking!
Lets hope that this fixes it!

Okay @Luthaf,

looks like installing the wheels that are not build in debug mode fixed the issue.

Perhaps this can be fixed with a release?
