tried to put all relevant information into the title above.
Further more:
running Win 7 64 Bit with Kaspersky Internet Security (no problems so far).
Downloaded the setup several times (in case of transmission errors) - didn't help. Also cleaned registry before new installation - also no effect.
In the task manager, process nor process structure is killable - only reboot helps...
For any suggestion or questions, please drop me a line via email.
Thank you very much for your support.
