Scenario: Users want to store files in SharePoint and open them from another website. The users are on a network with Internet Explorer (IE) 6 or 7 and Office 2007. This should not be an issue.
However, files of type .pps (PowerPoint slideshows) were opening in a undesirable manner.
Instead of opening in full-screen slideshow mode, the PPS files were opening in Edit mode inside of PowerPoint.
After doing a bit of research and testing, I believe this is the only solution that will allow PPS files to open in slideshow mode when using Internet Explorer and Office 2007. This site talks about it too. In a nutshell, it requires a client side configuration. Nothing on the server side can do the trick if the user is on Internet Explorer and Office 2007. It's not even an issue with SharePoint. It happens on non-SharePoint sites too.
This solution references this Microsoft KB article: http://support.microsoft.com/kb/299824/
Basically, each computer needs to have its registry changed:
- Start Registry Editor (Regedt32.exe).
- Locate and click the following key in the registry:
HKEY_CLASSES_ROOT\PowerPoint.Show.8 - Edit or add the following registry value:
Value name: BrowserFlags
Data type: REG_DWORD
Radix: click Hexadecimal
Value data: (see below)
It appears that Office 2007 changes the default value to "a", which means PPS files open in Edit mode. You can change the value to 8 (open in a new window in show mode) or 0 (open in the browser window in show mode), but this is a local computer change that would need to be done on each PC. Not realistic. :-(
Accessing the files in Firefox works fine: PPS files open as slide shows, no problem.
