Not sure if this is the correct topic, sorry if not...
One user has a problem when trying to open a PDF document stored in a content repository. She gets an error message, seemingly a Windows error that there's no program association for the file and she should set it in Control Panel.
Strange thing is she is able to open PDF documents from Windows Explorer, so the association should be fine, and other users can display the same file w/o problems.
So the problem seems to be user specific and I wonder whether there's any user specific setting for displaying document types. My guess would be that it's a GUI problem and she should try re-installing SAPGUI, but that would be the last resort.
