Symptoms
When you try to install the .NET Framework 4.6.1 on Azure Cloud Service virtual machines, the installer may fail with a "disk full" error ([HRESULT = 0x80070070 - ERROR_DISK_FULL]).
Cause
The .NET framework 4.6.1 installer now uses the %TEMP% folder to extract and install files. The %TEMP% environment on Azure Cloud Service Virtual Machines is limited to 100 MB, and this causes the installer to fail with the "disk full" error.
Resolution
To work around this issue, define a local resource for your Azure cloud service that reserves at least 1 GB of space, and then redirect the %TEMP% folder to this local resource.
