Installation of Python troubles

[bezan deme]

Dear supporters,
I tried several times to install the Python 3.5.0 (windows x86 executable installer) in my PC then in my LT and in both cases I failed. Last time, few hours ago, I tried it again, then it opened a window with a sole "cancel" button on it. I waited for 10-15 min without anything to seem to happen, then I tried to click on the open parts of the window just above the "cancel" button. Then it started a procedure of "uninstalling the Python" and after 5-10 minutes it delivered the message of "successfully uninstalling" a program which was neven installed, with a "close" button!I have downloaded the .exe Python version for 32-bit machine of 27,950KB size, for more than 3 times, in case s/th went wrong with the connection, from your main website.I tried it in 2 PC's and 3 laptops, with similar results (the installation process failed - unspecified error, etc.). Could you suggest something? Thanks,Demetris
