Invoking a .ppsm file from a web site

[Wi11y13]

We have created a PP presentation that is filled with macros and transitions.
We are using Office 2007. We have saved the file as a .ppsm file such that
when we open it it opens in slide show mode only for the users. This works
fine on our local machines. When we upload it to the web server behind our
portal though and open it it only opens as a presentation file that can be
edited etc which is definitely not what we want. We also get a message asking
us to open or save the file when we open it. If we sau open - it opens as a
presentation. If we say save - it saves to our individual drive and will open
it as a slide show but is then missing all of the interaction that is needed
from the web server. Again it was originally saved as a .ppsm file. Has
anyone else seen or experienced this and know of a solution? Anyone ever run
a slide show automatically from a web server?

Thanks in advance.

And the answer is....

The reg entry that needs to be edited is
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\PowerPoint.ShowMacroEnabled.12]
@="Microsoft Office PowerPoint Macro-Enabled Presentation"
"EditFlags"=hex:00,00,00,00
"BrowserFlags"=dword:00000008(was formally dword:00000010)
