           Product: Wine
           Version: unspecified
          Hardware: Other
                OS: Mac OS X

Mac OS High Sierra V10.13.6 + 
X-Quartz 2.7.11
tried to install a bookkeeping programme called "snelstart" via 
https://www.snelstart.nl/snelstart-download

installation starts but doesn't continue.

First tried to install with "Run as administrator", this gave an error code #
29559 at first try.

Then renewed try with "advanced installation", but no success either :
"The installer has encountered an unexpected error installing this package.
This may indicate a problem with the package. The error code is 29559."

Have tried all options (abort, retry, ignore), but no functioning programme.
