Re: [libreoffice-users] pptx files can't be opened when created with Impress 5.0.x

Hi :)
I mostly just agree with Tim Lloyd but with more detail and alternatives.


1.  Always avoid the 2007-2013 Microsoft XML format!!!

It's not just one format, for a start!  It's so inconsistently implemented
in each version of MS Office that they call each version a new
"transitional" format.  They just can't seem to quite implement their own
format properly or even consistently.  It's highly likely that you'd have
the same problem if you'd created the Pptx in, say MS Office 2007 and then
tried to open it in MS Office 2013.

By stunning coincidence that means people often have to buy a different
version of MS Office in order to be able to work together with other people
they know.  Possibly one of the few moves at the end of Steve Bullmer's
reign that seemed to help keep their profits up but all by accident of
course.

The older MS format (2003/Xp and earlier) "ppt" (without the X for XML) is
MUCH more reliable and much more consistently applied across their own
products and can also be handled better by almost all non-Microsoft
products.

Note that it was just after pretty much all other relevant software could
easily handle the older Microsoft format that MS suddenly produced this
newer format, allegedly releasing it "to improve interoperability" but
actually appearing to have quite the opposite effect.

So even if you are using a version of MS Office it's well worth doing
File - "Save As ..."
and using the older MS format.


2.  Have all the versions of LibreOffice been in the "Fresh" branch?
Please try the latest in the "Still" branch.  The way branches work is that
preceding versions of the same branch are unlikely to have fixed the
problem.  It's only by going to an earlier branch that you get in front of
a regression but really this is back-to-front thinking and generally things
tend to get a lot better rather than worse, despite what you may have read
here recently!  If you think of the 3rd digit as a "Service Pack" number
you get a clearer idea of what's going on.  The "Still" branch has a higher
"Sp" so it's fixed more of it's teething problems.


3.  Do you really need to do a PowerPoint presentation?  You can 'install'
LibreOffice on a usb-stick and then use it on almost any Windows machine.
I'm not sure how well it works as i know some places now lock-down their
usb-ports so that people can't copying anything.

4.  Also there are much better programs for writing presentations.
Powerpoint is one of the worst.  The only advantage with Impress or
Powerpoint is that they are part of the office suite and it may be easier
to use things created in other programs/elements/apps/modules of the suite
within your presentation.  Also it's what 'everyone' seems to be using.

Anyway good luck and regards from
Tom :)
