Contains installation.txt and backtrace.txt

pCon.planner 8.4 Update 2 doesn't install correctly: the progress bar of the
installer reaches the end, but the installation complete screen doesn't appear.
Trying to cancel the installation once it actually started also doesn't do
anything (didn't test if it's the same on Windows), so the only way to quit the
installation is by killing wineserver. Wine logs during the installation are
attached.
The files of the program are there though, but trying to execute it results in
the error from TLocaleReader "(-2147418113) Line 4 Column 19", and generates a
backtrace I attached below.
The uninstaller doesn't work either, with the progress bar not progressing at
all and a cancel button that doesn't cancel anything.
