Enabling WIN 7 64Bit screen saver after minutes of inactivity

Hi Support - have been through most of the posts in the forums however I wasn't able to locate a reply to my issue. I have a stand-alone touch screen/pc with a powerpoint show (PPTVIEW.EXE + the PPT as argument)consisting of a slide with to buttons that when tapped starts a (safety)video.

Working fine with the secure lockdown however it remains in the slide show and is not after e.g. 10, 15 minutes of inactivity starting the screen saver. I haven't been able to locate a screen saver exe or similar file that I could add to my secure lockdown configuration (windows\system32\....).
Anything to do?
Thanks in advance
Per

Do you have the "Disable Desktop" option checked in Secure Lockdown? If so, uncheck it and the screen saver should work.

The disable desktop is not checked.

What version of Windows are you using? Does the screen saver work when Secure Lockdown is not enabled and you're running the slideshow?

Win 7 Professional and yes, it's working fine. It stops when I activate Secure Lockdown. Is it possible to add the "screensaver.exe" as a background app?

Hi, sorry - it seems to be the PPTViewer - did some tests and apparently the viewer prohibits the screen saver to work. So obviously not your problem...
