Issue with impersonation level

[lukaspowerbi]

Hi,

I am getting the following error message when I go to all of my pbix.files in the past couple of days. It never happed before.

I have always use import as a data connectivity mode and it has been working great for more than a year untli now.

"DataSource.Error: An error happened while reading data from the provider: 'Could not load file or assembly 'System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Either a required impersonation level was not provided, or the provided impersonation level is invalid. (Exception from HRESULT: 0x80070542)'
Details:
DataSourceKind=SQL
DataSourcePath=az-use-rpt02;NF_Migration_Data"

How can I overcome this? Thank you.

Hi lukaspowerbi,

Reinstall .NET framework in your computer and restart your computer. If the error still occurs, run power bi in admin mode and check it works.
