Hi

I have developed one COM+ applicaition. Steps followed in developing COM+application-

1. Created class library project

2. Included System.EnterpriseServices namespace

3. Inherited class by Serviced COmponent

4. In Assemblyinfo.cs file i again inherited by system.enterprise service

5. Modified [assembly: ComVisible(false)] to [assembly: ComVisible(true)]

6. Added follwoing tag in assemblyinfo.cs file

[assembly: ApplicationName("MTSTest")]
[assembly: ApplicationActivation(ActivationOption.Library)]
[assembly: ApplicationAccessControl(true)]

7. signed the assembly using strong name

8. register the dll in MTS using following command using visual studio command prompt
regsvcs "......path of assembly with assembly name"

9. I could see the service with that name in Component Services -> Computers -> My Computer -> COM+Applications

10. i tried to export MSI using that service, MSI is created in that machine successfully at the given location. After that i tried to install that MSI from that location, but i got the following error-
"Error registering COM+ application. Contact you support personnel for more information"

Any pointer to this appriciated.

Thanks,
Anurag Bajpai

Hi Anurag,

I am moving this thread from Base ".NET FrameworkSetup" forum to the "ClickOnce and Setup & Deployment Projects" forum, since the issue is related to deployment. There are more deployment experts in the "ClickOnce and Setup & Deployment Projects" forum.

Thanks

Hi Anurag Bajpai,

The step you have taken is correct to use COM+ in .NET CLR based application. Actually if you don't register your component with COM+, it will attempt to auto-register when you first run it. That require administrator privilege.

The error message indicate that these component doesn't successfully registered. The reason is not easy to find, I have once met a similar problem with the antivirus software. Antivirus software's duty is to protect system register and that cause the COM+ register failed.

So delete the registered COM+ and do the following.
1. Login Windows as administrator.
2. If it is Vista/Win7 with UAC, please run your application as admin.
3. Do not manually register it, let it auto-register.
4. Turn off antivirus software protection temporarily when registering.
5. If it failed, run cmd as admin to register it.

Please inform me your test result.

Sincerely,
Kira Qian

Hi,

So you have tried auto-register? It appear to the services but still cannot run?
