Assembly Loading Failure


O

Olivier Matrot

Hello,
I have a .NET application that is called from within an installer custom
action.
The custom action is written in c# and called from a web site setup project.
The application is installed in the web site's bin directory.
It depends on libraries that are installed in the GAC.

The call to the application in the custom action is done through
Process.Start (not using shell execute).
Here is the fusion log :
________________________________________________

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or
assembly 'FaxBoxCustomer, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=cb1c7cff7286f087' or one of its dependencies. Le fichier
sp,cifi, est introuvable.

The problem is that 'FaxBoxCustomer' library is located in the GAC, and
that the application is working fine when launched from the command line !
In both case the user is the same.

Previously the libraries were located alongside the application.

TIA.

Hello, Olivier!

Are there any assemblyBinding elements in the
RTEFAXExpressCustomer.exe.config?

Consult the following article
http://msdn2.microsoft.com/en-us/library/yx7xezcf.aspx, particularly the
section about
"steps to resolve an assembly reference".

Assemblies aren't commited to the GAC during an MSI install until after your
custom actions run, so if you run code that has a dependency on a GAC custom
action it will fail to load it.

Thanks for that.
