Power BI Report Server - Install Problems - 0x80070643 fatal error during installation

Hi Anonymous ,

You can open Task Manager, go to "details", find if you have following, right click and "End Task":

- ReportingServicesService.exe

- RSHostingService.exe

- RSManagement.exe

- RSPortal.exe

- RSPowerBI.exe

Make sure none of them are running, then please try：

•  Run this command from an admin command prompt:
             sc delete ReportServerStandalone
• Delete the any files found under:
            C:\Program Files\Microsoft SQL Server Reporting Services\
• Rerun the new setup. and you should no longer get the blocking error
• Configure the new server via the RSConfig Tool (RSConfig.exe)

Hope it helps,

Best Regards,
