This could be due to an incorrectly configured host file as operating system hosts files map host names to IP addresses. An incorrectly configured hosts file can affect your computer's ability to connect to Adobe's activation servers.
Follow these steps to see if there is a problem with your hosts file and to reset it if necessary
Please check the
- Choose Start > Run, type %systemroot% \system32\drivers\etc, and then press Enter.
- Right-click the hosts file and select Open. Select Notepad for the application to open the hosts file.
- Back up the hosts file: Choose File > Save As, save the file as hosts.backup, and then click OK.
- Search the hosts file for entries that reference adobe (for example, 127.0.0.1 activate.adobe.com, or 127.0.0.1 lm.licensing.adobe.com) and delete these entries.
- Save and close the file.
- Restart your computer.
This solution worked for me before I lost patience with my Presenter subscription. Thanks.
