After doing this, I get the install-window (being asked for language and acception of the end-user-licence-agreement). If I click on "Next", it seems to install the toolbar (the progress-bar is getting green from left to right), but finally gives me the error-popup:
"Runtime Error (at 48:161):
DllRegisterServer failed; Code 0x80070005."
I got Thunderbird v1.5.0.9 and Skype 3.0.0.198 installed, both German versions.
Looking forward to an answer,
