Foxit reader after update asks for administrator account

Hello!

after last update of Foxit reader it asks our users to log in as administrator when opening PDF documents.

Foxit is updated, everything is installed, restarted, but still asks for administrator password for the first time when starting foxit or opening PDF document.

Details about patch:
301826
TU-023
Update For Foxit Reader (7.0.6.1126)



Can you check why is that happening and how we can sort it out?
Thanks,
Tomislav
