Powerpoint PPSX file

I have many powerpoint show files I need to open.  When I use LockDown it tells me there are not programs associated with the PPSX file.  But if I run it from outside of LD it works fine.  I also set it up to run as a background app.  If I set is as an argument to start with powerpoint.exe it it works, but powerpoint throws a lot of errors.

I would like to just add my powerpoint presentations to start from the PPSX file and run the slide show automatically.

Try enabling the System Lockdown > No Desktop option if it is enabled.

I get the same error no matter what type of file I try to open.  Even if I create an Icon that leads to a PDF or Word Document, it says, "the file does not have an app associated with it for performing this action. Please an install an app or, if one is already installed, create an association in the default apps settings page."

Did you move the Windows Library folders (and files within them) to a drive other than "C"? Secure Lockdown prohibits access to the C drive by the user.
