Hello,

recently the Documentation Center does not start in Mathematica 8 or 9 on my PC with Windows 7, 64 bit.
De-installation of Mathematica 8 and 9, re-boot of the computer and re-installation of Mathematica 8 did not help.
Accessing the internet is switched off in the Mathematica options.

I did not change anything in the Mathematica installation during the last months.
We have automatic security updates to all PCs in our intranet, however, other users in the intranet do not experience this problem.

Do you have any clue on the reason for our IT department which is trying to resolve the problem?

Thank you in advance and best regards,
Hannes Kessler
