Microsoft .NET 4.5 installation returned exit code 5100

The workstation may not have enough disk space to finish installing the Microsoft .NET Framework or upgrading it.

Acctivate utilizes the Microsoft .NET Framework, a programming model for Windows applications.  Microsoft .NET is a very popular framework, but Acctivate may need to install updates from time-to-time, such as upgrading to .NET 4.5 in Acctivate version 10.1.

During the upgrade, you will see something like this message on each workstation:


The above message should go away after a few minutes.  However, you may receive the following message on a workstation that does not have sufficient free disk space.  You will need to free up some disk space if you receive the following message, “Microsoft .NET 4.5 installation returned exit code 5100” when you launch Acctivate after an update has been installed.  Microsoft has some tips on freeing up disk space.


As usual, please contact our support team if you have any questions or have trouble installing the .NET framework updates.
