FileZilla Client wanted to install two PUPs on my PC.

Unchecky Info Tool has problems uploading the reports:

"curl_easy_perform() failed: Couldn't connect to server", maybe because of the proxy.

I've saved the reports as .txt files. If they would help i can post them here or mail them.

Edit: Using Unchecky v1.1

Thank you for the fast response, i have not found this thread before.

Now i configured WinHTTP correctly, so i guess it will work :)
