Cannot install WSUS 3.2 on a server with the .NET Framework 4.6 or later versions installed


View products that this article applies to.

Symptoms

When you try to install Windows Server Update Services (WSUS) 3.2 on a server with the Microsoft .Net Framework 4.6 or later versions already installed in it, then you may receive the following error message:

There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.

Additionally, the following message is logged on the WSUSSetup.log file:

Install WSUS: WSUS Installation Failed (Error 0x80070643: Fatal error during installation.)

Notes:

  • This issue also occurs on System Center Configuration Manager (SCCM) because the Software Update Point Site role depends on WSUS. WSUS is necessary for software update synchronization and compliance assessment scans on SCCM clients.
  • This issue only occurs if .the NET Framework 4.6 was installed before you install WSUS 3.2.
