To resolve this issue, try the following:
1. Check your Internet settings in the Control Panel
- Open the Windows Control Panel and go to "Internet Options" > "Advanced". If you do not see "Internet Options", change "View by" to "Small icons".
- Make sure all the entries from TLS 1.0 through TLS 1.2 are selected in the list.
- In the Control Panel, go to "Administrative Tools".
- Double-click "Services" and locate the service called "Background Intelligent Transfer Service".
- Right-click it and select "Properties" in the context menu.
- Make sure that "Startup type" is set to "Automatic".
Then, try downloading the codec or activating the program again.
2. Check your Internet Explorer settings
The program uses components from Internet Explorer which can sometimes cause communication issues.
- Check your Internet connection first and, if prompted, set your firewall or antivirus program to allow the connection.
- Check if Internet Explorer is running in offline mode. To do this, go to "File" and make sure that the "Work Offline" option is disabled.
- Go to "Extras" > "Internet Options". Open the "Advanced" tab. Under "Security", look for an entry called "Warn if changing between secure and not secure mode". Disable this as well.
- Check if Internet Explorer is accepting cookies. Go to "Internet options" and open the "Privacy" tab. Temporarily select the option to accept all cookies.
