Report Viewer failed installation

Question

Hello!

So I'm trying to install Report Viewer for Visual Studio 2019 and the installation keeps failing. I updated Visual Studio to the latest version, thinking that this might solve the issue but it didn't.

The message that I get is the following:

• The install of "was not successful for all the selected products. Object reference not set to an instance of the object.

So clicked on the install log to see and this is the message I got:

Answer 1

Hmm, almost seems like it is having an issue enumerating the installed instances of VS. You might need to send the setup logs to the SSRS team so they can diagnose what is going on. On their marketplace page they do recommend trying to install the previous version first if you run into an issue. Then you can upgrade to the newer version in VS. You can also post a question there asking for help from them.

Hi MariaBarna，

Please go to C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin, then remove the Microsoft.SqlServer.Types.dll if it exists.

If it doesn't work, please try to repair your visual studio.

Best Regards, Dylan
