Hi :)
Yeh, i've just googled it and seen tons of problems with the Windows
installers.  I think we can safely assume there is nothing wrong with the
download at this point.

I'm not sure i entirely trust any of the links i give below.  The first one
that's from is a forum thread so the answers could be from
any random nutter.  So it might be worth comparing some of them to see if
they corroborate each other at all.  Also use your normal search thing to
get a rough idea of what commands do or what any suggested registry keys or
other stuff they suggest is likely to do BEFORE actually doing what they
suggest (unless it really looks harmless and doesn't touch the registry).

This sort of thing looks really dodgy to me so i'd normally not include
it.  The main reason this time is just to show the sort of 'help' that
could well be really dodgy;
Note that MS provide support that looks very similar (ie trust us and just
click on this link and it'll run a process that does a bunch of stuff we
are not going to tell you about) with MS i do actually trust that their fix
might work but i think it's bad as it encourages people into bad habits

This sort of thing shows you what to do so you get more idea about what
it's doing.  Ignore step 1 as this was written by a different company
tryign to cope with the weird and wonderful craziness of Windows systems
(err and only do step 2 if you've hunted around a bit to make sure it's
safe advice);

I thought this was an interesting tangent
I'm fairly sure it's not what is happening but it's nice to have a list of
what some of the most popular file-types are for.

Good luck and regards from
Tom :)

We went off on a tangent around here somewhere.  There still seems to be a
problem installing LibreOffice on this Windows 7 machine.

The download is an msi so that IE issue doesn't seem to be the problem.
The installer's file-size is 215,652kb, so that's around the 220Mb figure
try to remember.  We've not tried an md5sum or Sha check to make sure but
it really looks like the download itself was probably NOT the issue.

That looks about right for the LibreOffice installer. Checking the
checksum would help confirm that it hasn't been corrupted.

 Firefox has installed successfully so it's not that the user doesn't
understand the weird blockers Win 7 tries to put in the way of installing
anything (which usually seem (to me) more intense when trying to install
non-MS stuff)

Win 7 is still claiming that the installer is not an installer, even
the installer is an msi file.  The exact grumble is
"Windows Installer    This installation package could not be opened.
that the package exists and that you can access it, or contact the
application vendor to verify this is a valid Windows Installer Package."

Could be a problem with the Windows Installer service. From previous
discussion, it looks like this is on Windows 7 without Service Pack 1 (and
possibly other updates)? So first, install Windows 7 Service Pack 1 and any
other updates offered by Windows Update. The Windows Installer service is
sometimes updated, and newer installers don't always work with an older

I've also seen mention of people working around this error by creating new
Windows user account and logging in to that to install. Probably means
there's something not quite right in the original profile. Provided you
install for all users rather than just the current user, you'll still be
able to use the application from your usual login.

 Anyone any ideas about what might be different enough between the Firefox
installer and the LO one to be causing this issue?

It looks like Firefox uses an .exe installer, rather than .msi, so there
may be many differences. Even if Firefox's is just an .msi packaged within
an .exe, it might work with an older version of the Windows Installer
service than LibreOffice's does.

 i tried twice to download and install the newest libre suite. the
download went perfectly both times but when i told my computer to
install them i got the same error message both times. it said
something like 'this is not a windows installer'  and to 'contact the
makers' or something like that. i love libre office and have used it
for many years on several different computers with windows , xp and
vista and have never has anything go wrong with anything, ever. this
computer is running windows 7 home premium without sp1 so far. what
should i do?

 What is the extension of the download you try to install? Often IE
changes the extension of the file in .man instead of .msi.
Kind regards

 Most everyone I deal with locally will not use IE due to its "issues".
I suggest using Firefox or Chrome for downloading the files.  They work
much better than IE and you can add more "useful" security options to
that make it easier and safer to use than IE.

Actually, the newest version of Firefox for Windows has an ability to run
the file after the download DIRECTLY from the download history options -
either by clicking the "blue" download arrow for the last few downloads,
via the full history section via the Tools>Downloads option.  This works
better than the IE run file after downloading option.

I currently have access to Win7 laptops, but I have had not trouble
downloading the files via Firefox or Chrome and installing them.  I
upgraded a Vista [32-bit] laptop to Win7 Pro [64-bit] due to Vista's
me the same type of errors for many different packages, ones that
well on XP and Win7 Home.  I did have a few times where XP did not like
install .msi install versions when there were .exe install versions

So please install Firefox or Chrome browsers and download the .msi files

ALSO, MS sometimes changes its internal package installer used to
run/install .exe and .msi files.  I had to update the installer via MS's
web site free downloads section.  Sometimes this needed internal package
not updated/upgraded via the automatic Windows Update system.  This has
happened to me once with XP and twice with Vista.  This solved the type
errors you are seeing, in Vista mostly.

Win7 without SP1?
Have you been installing all of the Win7 updates since you installed the
Win7 OS, or first ran it when you got the Win7 system????  If you did,
even though the OS install did not have SP1 included, then with all of
MS updates you should have all of the packages that are included with
That is what happened with a desktop that I have that came with Win7 Home
Premium with no indications of SP1 was installed.  Now it shows SP1 in
Control Panel>System window.
