We’ve updated our MSI and agent installer to support .NET Framework 4.5 and above, for maximum capability and security. This means Atera agents can effortlessly be installed on widely used operating systems such as Windows OS 10 and Windows Server 2016 (and above). The .NET Framework 4.5 is a basic requirement for use of the most popular software and browsers, in addition to current Microsoft patching and bug fixes.
We are phasing out support for .NET Framework 3.5, which is outdated, and no longer secure, starting on June 23, 2019. The phase-out will officially take place in 6 months, on December 23, 2019, at which time support will end. If your OS is Windows 8.1 or Server 2008 or later, we’ll automatically update it for you. There's no need to do anything.
If you, or some of your customers, are on older systems, we recommend switching over as soon as possible, as Atera will no longer be able to fix system bugs or add new features to agents running on the old framework. To switch over, follow the instructions below:
If you are using Windows XP or Windows Server 2003: Please upgrade to a more current operating system.
For Windows 7, Windows Vista, and Windows Server 2008: Install Microsoft Service Pack 1 (SP1) or Microsoft Service Pack 2 (SP2), as well as .NET Framework 4.5 (https://www.microsoft.com/en-us/download/details.aspx?id=30653), as specified below:
- For Windows 2008 with SP1: Install Microsoft SP2, as well as .NET Framework 4.5
- For Windows Server 2008 with R2 version, excluding service pack: Install Microsoft SP1, as well as .NET Framework 4.5
- For Microsoft Windows 7: Install Microsoft SP1, as well as .NET Framework 4.5
- For Windows Vista with SP1: Install Microsoft SP2, as well as .NET Framework 4.5
Note: Please don’t uninstall or reinstall the Atera agent on an operating system running .NET Framework 3.5 until after you have followed the instructions above. The agent supporting .NET Framework 3.5 cannot be reinstalled.
