Hi Richard.
the file is gspawn-win32-helper.exe
My diagnosis is that when unzipping with Windows Extract, McAfee
kicks in and finds a problem with the recent versions of the file.
When I WindowsExtrtacted the Nov30 download (I usually use 7zip as it
is MUCH faster) I got an error message that I had been protected from
an (unspecified) file. And denemo provided me with the familiar
reports about Typesetting.
So I looked in the McAfee "History" and found that it didn't like
gspawn-win32-helper.exe and had protected me several times from it!
The official Windows denemo 2.5 download, treated in the same way
did not upset McAfee.
So I tried copying gspawn-win32-helper.exe from the working version
into the bin folder of the faulty Nov30 and it just copied it in - no
messages. Trying to copy in a second version flagged up that there
was already a copy in bin. Therefore McAfee had registered it as
dangerous and simply not copied it over. And it has been deleted from
several of the other non-typesetting versions.
My assumption is that using 7Zip skips past McAfee, BUT when I try
to run denemo McAfee kicks in and deletes the gspawn-win32-helper as
it is missing in all the versions that don't typeset. BUT the
deletion isn't reported.
SO there must be something different in the most recent versions
Indeed there is, because although compiled from the same source code
the compiler is a more recent version and will generate different
sequences of bytes, which give >150Mb of them results in accidental
matches with virus "signatures".
[...]I
have a work-round if I want a more up to date version than Oct
30/Denemo 2.5 - just overwrite gspawn-win32-helper.exe.
yes, or get a better virus checker - I notice that on installing the
operating system from Microsoft directly it does its own checking (it
says) and doesn't suggest installing third party software to check for
viruses...
