To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

As far as I know, the error message means that the Report Viewer is not installed on your server machine OR the version installed does not match the one you are using.
I suggest you could download ReportViewer.exe from the Microsoft Download Center,the ReportViewer control redistributable is a self-extracting file named ReportViewer.exe that includes an .msi and other files.

Did you install report viewer runtime on the server?

Hi Kumar,
As far as I know, the error message means that the Report Viewer is not installed on your server machine OR the version installed does not match the one you are using.
I suggest you could download ReportViewer.exe from the Microsoft Download Center,the ReportViewer control redistributable is a self-extracting file named ReportViewer.exe that includes an .msi and other files.
Link: https://www.microsoft.com/en-us/download/details.aspx?id=45496
Notes:
Different versions of the ReportViewer control redistributable can be installed on the same computer.
When you run ReportViewer.exe, the following files are installed in the Global Assembly Cache folder on the deployment computer.
More details, you could refer to below article.
