Related to the above is the possibility that there is corrupt files in the system. For example after having installed an application and it has given a problem. This can affect other components and applications that you have installed.
Steps to avoid the error
After explaining the main causes of error 0x800F0950 in the .NET Framework, we are going to explain what we need to do to fix the problem. A series of simple steps that we can carry out and points to review on our device.
The first thing we must do is check that we have Windows updated correctly. This can be the solution to many problems of this type, so you have to review and install any new versions or files that are pending.
To do this we have to go to Start, enter Settings, we will Update and security and there it will appear whether or not there is something pending to install. It is possible that a pending update was left and did not complete correctly. There it will appear and we have to give it to update manually.
Once this process is finished, we will simply have to restart the computer so that the changes are made correctly and have the updated files ready to avoid any type of problem.
Check that there are no corrupted files
Another common cause of error 0x800F0950 is corrupt files on the system. In part it is related to the above, with the updates, since it has happened that something has not been installed correctly and has generated a conflict. But it can also be due to some program that we have added or any component that has stopped working as it should.
In this case, what we are going to do is check that there are no corrupted files and fix it if necessary. We have to go to Start, we write Command Prompt or CMD and we open it. Then you have to run the sfc / scannow command.
What this function that comes integrated with the system does is check that there are no files that are damaged and repair it if necessary. It is a process that can take a few minutes. When finished we restart the equipment so that everything goes correctly.
Install .NET Framework from Windows Features
We can also install .NET Framework from Windows features, an option integrated into the system and from where we can add or remove certain components. This could download some problems, such as connection failures or that the file we are trying to install is corrupted.
We have to go to Start, open the Control Panel, click on Programs, enter Activate or deactivate Windows features and there we will see a long list with multiple options. Among them we will see that of .NET Framework.
You have to uncheck the box (if it is checked) and then we turn it back on. Then we click OK and restart the computer. In this way we will have installed this feature through this method.
Restore the system to a previous point
There may be a corrupted file or a problem with a previous update that was not resolved properly after performing these steps. Luckily Windows itself has the function of restore the system to an earlier point where the equipment was working properly.
In this case we have to go to Start again, we search Create a restore point and we open it. You have to click on the System Restore button and it will recommend a point at which everything works fine. However we can select another point manually.
For example, we can do this if the problem has appeared after installing a program or after updating Windows. What we do is go back to a previous point where the system worked fine and did not show us the error 0x800F0950.
Use the .NET Framework Repair Tool
One more alternative if all this has not worked correctly is to make use of the repair tool of .NET Framework. For this we have to go to the official Microsoft page. This tool is generic for troubleshooting many types of problems with the .NET Framework.
We have to download the file and then run it. It supports different versions and it can come in handy when any similar error appears and we have not been able to solve it by the methods that we have explained previously.
Ultimately, the .NET Framework error 0x800F0950 can appear for different reasons. It can happen due to having corrupt files, an update that has failed or simply not having installed the latest version. We have talked about what we should do to fix it.
