I am getting the same thing in VS2005. The tooltip says something to the effect that it's trying to cast a variable with a number that is greater than infinity. To me, it sounds like the component itself is trying to do that and not the act of declaring the component, but I need to prove it before I can send a defect report back to development. This sucks!

Are you guys running on Vista?
This error seems to be common with Vista updates...I also found a few mentions of it occurring in Visual Studio 2008...

I've read that if you have the "Windows Modules Installer" disabled that you will encounter this error.

To fix this:

• Go to service management console (Start -> Run -> Services.msc)
• Make sure that the 'Windows Modules Installer' is enabled
• Then check for updates.

After updating hopefully your issues will be resolved.

I have resolved this error by enable the service WIA in windows 2003 ..
but now i am getting the following exception.

Exception Details: System.UnauthorizedAccessException: Creating an instance of the COM component with CLSID {4EC4272E-2E6F-4EEB-91D0-EBC4D58E8DEE} from the IClassFactory failed due to the following error: 80070005.

What to do now????

This is happening because your application does not have sufficient security rites to use the COM component.

You should look up Security in .NET...check out this article to get you started.

I am getting the same error . I have activated WIA servicethru service.msc and have done the Launch and Access settings in Dcomcnfg tool on Windows 2003 for WIA devie manager component

Still Error is there while instantiating WIA manager class. It works fine on development machine but gives error on web server

If you are using the wiaaut.dll you need to do a regsvr32 in the server.

You also need to make sure that the ASP.NET account and worker process have permissions to use the DLL and likely the directory that it's in.

Give ASPNET permissions to read, write, and execute for now and see if it works
