Bug comments restored from Gmane.org:

It seems that WINE Setup API has problem parsing comments in .INFs. For
instance, when trying to install HTML Help Workshop above the Setup fails with
the message:

Incorrect INF file syntax in section 'HHWDestinationDir             ; Ask user
for custom destination'

Uncompressing the self-extracting package and removing the comments avoids the
problem:

cabextract htmlhelp.exe
  mv htmlhelp.inf htmlhelp.inf.orig
  sed -e 's/;.*$//g' htmlhelp.inf.orig > htmlhelp.inf
  wine setup.exe

The strangest thing is that the ';' is already being considered in
value_name_state() in dlls/setupapi/parser.c.

I guess the problem must live on PARSER_string_substW() in
dlls/setupapi/parser.c, which is called by GenFormStrWithoutPlaceHolders16.
Unfortunately there isn't available information about this later API.
