Can you open Adobe Reader by itself? If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].
If you cannot open Reader by itself, try to disable Protected Mode in the registry; download, unzip, then run the attached registry script

Thanks for the reply.
No, I can not open the Reader itself without this error message,
and even at a right-click on a PDF-file are administrator rights required.
Before I'll start the test with the zip file: What I do not understand is this. The Protected mode is still really important and so wanted by Adobe since Ver. 10X
When II turn off this permanently, will I loose this security feature??Greetings
Adobe insists that Protected Mode should not be turned off, as it is an important security feature.
On the other hand it causes so many problems that I routinely suggest to turn it off.
But it has also come to my attention that turning Protected Mode off, then back on again, many of these problems magically disappear. So maybe you want to try this?
Please help me in understanding your problem better as on normal Win7 machines we don't get these issues.
Can you please let me know the following:
1) Exact operating system like Win7 (32bit or 64 bit) (Home, Enterprise or Ultimate) (Goto Computer , right click and you'll see the details in Windows Edition and system)
2) Any antivirus/ antimalware/ encryption software installed in your system? (It might be stopping Adobe Reader to open with protected mode enabled)
3) Are you login with any specific kind of user or normal administrator user ?
4) Is your system a part of any special file system?
5) Have you installed Adobe Reader at the default location (For 32-bit systems it is C:\Program Files\Adobe\Reader 11.0 and 64-bit it is C:\Program Files (x86)\Adobe\Reader 11.0 ) or any other location?
1. It is Win7 Prof. 64 Bit
2. I am using Norton Internet security which includes anti-virus and firewall
3. I login as a User - not as an adminstrator. (Althouhg the problem was the same when I switched to th Admin-login or tried to execute Adobe-Reader as Admin)
5. It is installed under ´C:\Program Files (x86)\Adobe\Reader 11.0" (By the way: The Problems poped up after the last update to version 11 - not before.)
