Mircosoft.ReportViewer.WebForms.dll fails to load

I've just deployed a website to a test server and when I hit a web page that uses the ReportViewer control, I get an error "Microsoft.ReportViewer.WebForms.dll failed to load...". I've searched all hard drives attached to the server and the DLL is not there. I understand that this should be part of the .NET 2.0 framework redistributable package and should live in the WINDOWS\assembly folder. It is not there.

The Add/Remove Programs dialog from the Control Panel shows the .NET 2.0 framework as installed. This is a windows 2000 server box running IIS 5.

Anyone got a clue as to why this DLL would be missing?

Thanks,

Mike

I am having similar issues. I've manually copied the Microsoft.ReportViewer.WebForms.dll from my development PC to my production server's Web app's Bin directory, but am unable to view the ReportViewer's icons such as Export, Print, etc. They're just red x's.

What is the best way to publish the Report Viewer?

The cause of this problem is because the ReportViewer is not installed on the Virtual (Production) Server. Install the ReportViewer by running ReportViewer.exe on your Virtual Server. You can most likely find the ReportViewer.exe on your development machine at C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\BootStrapper\Packages\ReportViewer\ReportViewer.exe

Installation instructions(see link below) are easy to follow & unlike everything else you've probably been wrestling with, this installation should be painless.

Migration Wizard Fails Interop.DSO.IDBGroup90Ex

I am attempting to convert several 2000 AS databases to AS 2005. I have not been able to successfully convert any databases. The error message is:

Unable to cast COM object of type 'System.__ComObject' to interface type 'Interop.Dso.IDbGroup90Ex'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{CE55E9E9-9597-4214-B21F-30C7683467B1}' failed due
to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

I have attempted to convert the FoodMart sample database and it also fails to convert. I have unregistered and registered all DSO related dlls. The problem still persists. I have attempted to convert at least 4 other databases and they all fail. The failure point occurs during the conversion of the Cubes.

Problem solved. Unfortunately, I am not sure which step actually solved the problem. I will state both here.

1. I registered all of the dlls associated with DSO, which reside in the directory: C:\Program Files\Common Files\Microsoft Shared\DSO using regsvr32. BTW, I don't believe that this solve the problem, but I have state it here because of item 2.

2. I downloaded and installed Service Pack 2 for SQL 2005. The Service Pack installation forced a reboot so I not exactly sure that it was the cure. My gut says that it was an not option 1.

Anyway, I hope that this helps anyone that has been struggling with this issue.
