Hi GigyJ,

Have a try running the InstallUtil tool from the Visual Studio 2008 Command Prompt.

Hope this helps.

Are you mixing framework versions? You'll get that kind of error if a 1.1 assembly tries to load a 2.0 assembly.

Looks to me it is trying to load 1.1 assembly.

Microsoft (R) .NET Framework Installation utility Version 1.1.4322.573

How can I get rid of this ?

Thanks
