I don't understand what you are talking about.

Regression testing is not an application, it's a method for finding the cause
of an issue when it results from a change in the code. It's not meant to be
done by average users and it can't be made universal as the regressions are
unpredictable.

It consists of iterating through the commits (individual changes in the code)
between a known working version and a non-working version until the first
commit that causes the issue is found. You have to compile Wine at each step
and then test the application with the intermediate build.

The instructions given are an example. They use git because that's what the
project uses for its own builds and it has an easy to use bisect function that
facilitate the regression test by using a dichotomic algorithm.

You have to adapt the instructions to your own building environment and
requirements.

If you use a pre-build Wine package then it's normal. Wine 6.0.1 packages are
now old and were built against old dependencies so when you use it, it tries to
load old libraries that are just not there.

That's why the regression test requires building Wine on the current system, so
Wine loads libraries that are current installed.

I just tested the demo on Wine 7.13 and it works out-of-the-box, so we need
more info on what is happening on your system and the first thing you can do is
provide the log that I asked earlier.

Regards.
