I have a custom browser/app that opens PDF's within the app which can sometimes cause issues. I found that if I set Reader X to not open in the browser (Edit>Preferences>Internet - uncheck "Display PDF in Browser") that this does resolve most issues. My problem...when changed this only affects the current user/profile that's logged in. Potentially there can be dozens of users on these laptops. The other setting is when opening a PDF, I get the warning about Protected Mode not being able to be used due to the current configuration. I can select "Always open with Protected Mode disabled" and I no longer get the message; but again, current user/profile only.
Is there a way to set these settings for ALL users/profiles? Running Win7 (32bit) with Reader X.
