Wix - ComPlusAssembly - Could not install type library

I'm new to Wix and I have ran into a problem that I'm obviously not able to solve on my own, so any help will be very much appreciated.

Quick background: I'm representing a software vendor building a comprehensive suite of SOA based applications for deployment in large enterprises. Our architecture consists of many layers which may be installed/upgraded independently, so I'm building several installers, composing from the ground up (like: platform, core framework components, service layer, business layer, application layer, etc.).

Software versions:

-Wix 3.5.1309.0 (wix.dll)

- Visual Studio 2008, .Net 3.5

- Build OS: Windows 2008 R2 Standard 64 bit

- Deploy OS: Windows 2008 Standard 32 bit

My problem is in regards to installing .Net assemblies in COM+ applications. I keep on getting the error "Could not install type library". I have been reading all the documentation that I can find, and I have been google'ing for several days now. I find quite a few posts on the topic, but I'm still not able to resolve the issue.

To isolate the problem I have extracted the issue into a separate installer. First I run the main installer:

1. Installs all assemblies into GAC, including the one to be installed in COM+.

2. Create local users and groups.

3. Create the target COM+ application, including roles etc.

4. Installs the target assembly, and the companion typelib, in a folder (to remove any GAC lookup issues)

This installer I can install/repair/uninstall, everything works fine.

Then I run the minimum installer containing only the issue, which tries to:

1. Install the assembly in an existing COM+ application (server), referencing the pre-installed .dll and .tlb.

The install fails, and the log is showing:

MSI (s) (AC:64) [19:16:01:127]: Invoking remote custom action. DLL: C:\Windows\Installer\MSI1BAB.tmp, Entrypoint: ComPlusInstallExecute  
ComPlusInstallExecute:  ExceptionInfo: Code='0', Source='System.EnterpriseServices', Description='Could not install type library 'c:\Program Files\MyManufacturer\ComPlus\WDA.ServiceProviders.Update.11.tlb' into application 'WDA.ServiceProviders.Update.11'.', HelpFile='', HelpContext='0'  
ComPlusInstallExecute:  Error 0x80020009: Failed to invoke RegistrationHelper.InstallAssembly() method  
ComPlusInstallExecute:  Error 0x80020009: Failed to register .NET assembly  
ComPlusInstallExecute:  Error 0x80020009: Failed to register assembly, key: MyAssembly  
ComPlusInstallExecute:  Error 0x80020009: Failed to register assemblies  
Action ended 19:16:02: InstallFinalize. Return value 3.  

I also notice that the rollback removes the COM+ application, even though it was not created by this instal开发者_如何学编程ler.

I can install the assembly manually, using the Server Manager, from the same physical file that the installer is referencing. After manually removing the component from the COM+ application, then the installer works!

Also, why do I have to supply a typelib in the first place? The EnterpriseServices.RegistrationHelper is generating the typelib on the fly anyway.

This is the minimum test installer that is failing:

I have the same problem. Ive tried Wix 3.5 and 3.6.2012.0 and it hasnt worked with either. It works if

1. I use regsvcs first
2. Delete the component
3. Run the msi and click on Ignore when a message comes up about the application already existing

Did you manage to find a solution?

First, you might try upgrading to the latest version of WiX v3.5. There were some bug fixes in COM+ at the end. If that doesn't work, take a look at the open bugs around COM+. There are a couple known issues with the installation code due to complexities in COM+.

If any of those bugs sound applicable maybe you can help fix them with the community?
