Hello,

Could you please try to install .NET Framework version 4.7.1? Microsoft .NET Framework 4.7.1 supports Windows Server 2008 R2 SP1.

But if some reason there is no way to install it then you can download and install .NET Framework version 4.0.0 and use SQLBackupAndFTP for .NET Framework version 4.0.0 which you can download by clicking “SQLBackupAndFTP for older .NET Framework v4.0.0” at https://sqlbackupandftp.com/download page.
