Hi @Dukat-2021
What is your version of .NET framework on the server? If it is v4.0, then you don’t need to change it. If it is v2.0, then you can refer to below steps to update .NET framework IIS.
- Open IIS manager.
- Click the “Application Pools” node.
- Find the corresponding application pool that your web site/virtual directory use. By default there is a "DefaultAppPool" application pool.
- Right click the application pool, and then select "Advanced Settings".
- Now we can change the ". NET Framework Version".
