I am trying to install the .NET Framework without success. The following error message is displayed:
This problem may occur if the temporary folder of Windows Update has been corrupted.
We can refer to the following steps to rename this folder:
1. Open a command prompt and type: net stop wuauserv
2. Click Start, click Run, type: %windir%
and press Enter.
3. In the opened folder, rename the SoftwareDistribution folder to SDold.
4. Open a command prompt and type: net stop wuauserv
Try to install .NET Framework again.
Thanks to oussamodas
