issue in loading dataset in powerbi

[Aankita1230]

I just installed the most recent version of PowerBI desktop on my laptop, but now I receive the error "Loading
Orders
Failed to save modifications to the server. Error returned: 'The following system error occurred: class not registered '." 

Please help in fixing this issue.

Hi  @Aankita1230 ,

Usually we recommend users to download Power BI Desktop using the official download link rather than through MS APP Store, if you are in the latter case, please reinstall the official website download link version.

Download Microsoft Power BI Desktop from Official Microsoft Download Center

If your version is fine, try clearing the existing Permissions in the data source settings and select the data source as new and enter the credentials. Finally restart Power BI Desktop and run it as administrator.

Hope it helps！

Best regards.
