--- Comment #12 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

adding stable download link via Internet Archive:

https://web.archive.org/web/20210708082931/http://zahlenbasar.de/MA_DL/setupgs5_6.exe

I'm pretty sure you must have seen a dialog box while retesting, which states:

"Zugriffsverletzung bei Adresse 7DAA0EA5 in Modul 'shell32.dll'. Lesen von
Adresse 00000000."

After dismissing the dialog, the installer runs further and indeed completes
without live-loop (copies files). It *appears* to be fixed but in fact it's
not.

Commit
https://source.winehq.org/git/wine.git/commitdiff/98d43c5dcfb28183667d874d4c07dfd9bb434149
("shell32: Calculate known folder paths from parent and relative path."), part
of Wine 6.10 release, introduced a regression which causes a NULL pointer
exception the reworked shell32 code. The exception is handled by the installer.
Unfortunately this causes code paths being skipped, related to the original
bug.

I've created bug 51425 ("Mathearbeit G 5.6 installer reports null pointer
exception in module 'shell32.dll' starting with Wine 6.9-142-g98d43c5dcfb") to
track the regression.
