Could you please re-post your question in English so the greatest number of members would be able to help you?
Could you also give us more details on your problem? What Operating System and which product are you trying to install?
I understand that you installed the program and were prompted to restart before the installation could continue, yet even after restarting, you continue to get the same prompt each time. Is this still occuring?
Yes you understood right. Same prompt occurs still.
Thank you for confirming the issue in English. However in order to provide advice, could you also give us the Operating System exact product are you trying to install?
A screenshot of the prompt could also be helpful.
F-Secure Safe Network Installer.
Here you can see screenshot.
This same prompt arrives every time. No matter how many times I reboot computer. I´m using Windows 8 Pro. Having some update issues with it too. I don´t know whether it affects this but I´m not able to run all the windows updates.
Thank you for the complementary information.
