Question

Merge module using .NET Installer class and Main project using Wise 7.0 -1001 - InstallLib.dll Unknown error

Asked by: Abh4IT

When I create an merge module using VS.NET 2005 and creating a setup project in .NET It works fine with compiling and also works as expected with executing the .NET based custom action defined in msm as a .NET installer class implementation.
But When I use the msm from my already existing MSI created using Wise Installer 7.0, I compile and when I tey executing it throws the error 1001 InstallUtilLib.dll Unknown Error. Since I want the code to be simply written in VB.NET (instead of complex stuff in C++) I would like to have this working with .NET itself. May places I checked says it is due to the context not set to .NET 2.0 correctly.  We are still struggling to find asolution for this. If any one of u have come across this pls help us with inputs.

Thanks
Abhilash

Hi, I guess I assumed .NET means Windows and The question is using Wise Installer Studio 7.0 together with VS.NET. The question should be relevant for all working on the deployment aspect using Windows Installer

Hi,

At last we figured out the issue. The issue is when you want to run .NET based custom actions, Windows installer is not able to identify the exact .NET version (CLR version) and load the appropriate InstallLib and excute the .NET based custom action dll. This could be resolved in the following way
CPP Application have a method which takes MSIHandle as parameter
-Use CLR Hosting to hoat a specific version of .NET (C++)
CorBindToRuntimeEx
-Load the assembly from within this hosted CLR using DefaultApplicationDomain or created new application domain
ExecuteInDefaultDomain
Build with .NET support (/clr )
make the .NET method static
Now you can have CallDLLFromInstallation - with MSIHandle as parameter
-Other option is - Dont depend on .NET;-) Write CPP code to do full operation.
