Hi,
I get this message when I try to open a PowerPoint file that was
created with office 95 -97 in office 2007. I can still open this file with
office 2003 (pre sp3) as SP3 creates blocking of file types from previous
versions. Is this still an issue in office 2007, and if so how to allow
earlier versions to be opened.

Cheers!

Glenn

If I recall correctly, PPT 2007 will not open PPT 95-format files. 2003 (pre
SP3, as you are aware) will, though, so open the files in 2003 and re-save
them as regular PowerPoint (2003-format) files. 2003 has an option to save
as "97-2003 & 95" format. That "and 95" part wll get you. Just save it as a
regular PowerPoint file, which in 2003 is really the equivalent of a 97-2003
format (without the "and 95" part), and which all versions except PPT 95 can
open.

I'm sure someone will be along shortly to correct me if that's not right.

AsEcho said

If you already have SP3 in 2003 you can get it to open earlier files in the
registry by navigating to:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\PowerPoint\Security\FileOpenBlock

and changing the "FilesbeforePowerPoint97" DWord to 00000000

Dear John, lease read what I posted in other posts concerning opening office
95 in office 2007 respectivly powerpoint 95 in powerpoint 2007. If You as MVP
have the chance to discuss this with Microsoft: we users do URGENTLY NEED a
converter-pack making it able to 1. view elder files and 2. convert them for
further use. Without any elder version of office and without restrictions. As
I wrote there in the other posts: companies do have any former document
inside any archiv in elder office-file-versions. We cannot convert thousands
of files by hand merely for ensuring we can open them in the future.
Besides: the reg-key You mention is what I miss in 2007. The ADM-Files for
2007 give the oportunity to block some file-types, beside others the older
office-files. But the contrary is not supported: even if I deactivate these
settings, I still cannot open powerpoint95-files in 2007. Thousands of files
in my company would be inaccessible when we would upgrade from 2003 to 2007.
Please let us know when Microsoft enables us to upgrade to 2007 by giving us
access to our elder files ;-)) Thanks in advance.
