Among all the existing instant messengers, Skype,perhaps, is one of the most popular. However, users of "Windows 7" sometimes have problems with this program, and they simply can not install it.

Firewall
Quite often, Skype is not installed on Windows 7 due to the fact that the firewall considers it a malicious program and, therefore, blocks its operation. To fix this, do the following:
- Log in to the "Control Panel" and find the firewall in it.
- Go to the firewall settings and select "Enable and Disable" in the main menu (on the left).
- In the window that opens, check the lines "Disable the firewall" (two of them) and confirm the changes.
