MSI is a standard and the MSI switches when being called from MSIEXEC.EXE are always the same.

I have a feeling however that this is not what you mean...

Supported switches are usually embedded in an Executable or Command. 

what about the exe's? I'm actually now looking to get the switches for the setup.exe. The same SEP switches don't seem to apply to SEP XPe.

For most executables, and depending on how they were coded, you will be able to get the switches from a command line.

Open a Prompt, drag and drop the Executbale into it.

[xxxx].exe /? will give you the command line (switches/options) if any.  Other times, the EXE will be coded to open up and use an embedded MSI package which will use the standard MSI switches. 

Just speculating here, as I do not use either...

But try it out and let us know please.

Here is our MSI command line reference for Symantec Endpoint Protection 11.0

I know it is not exactly what you are looking for but maybe it will help.

Grant-

These are worth a shot.  I'll post back if these same switches work on the SEP for XPe single file exe.
