I tried installing Veeam MP6 on an existing server with Windows Server 2008 R2, IIS and ASP.NET 3.5. I kept getting an error stating “Error during ASP NET enabling. Error = 2”.
The same error appears in the VesWizard setup logs located in C:ProgramDataVeeamSetupTemp.
[10:27:33:21]: ***Veeam*** NT64 property is set
[10:27:33:37]: ***Veeam*** Internal error
[10:27:33:52]: Error during ASP NET enabling. Error = 2
After investigating I needed to install .NET Framework 4.0 or later on the machine.
Currently the latest setup files for .NET Framework 4.5 can be downloaded from http://www.microsoft.com/en-us/download/details.aspx?id=30653
Note that installing .NET Framework requires a reboot of the machine. Everything is running fine at my machine right now!
