[RESOLVED] RegAsm and Windows 7

Hello folks!

I just developed one COM interop component in VB.NET 2010. Everything is fine, on my development machine everything works properly.
I would like to distribute this dll with all dependencies on other machines as well.
I just did a test on the brand new installation of Windows 7 x64 and x86 Enterprise version.
The following command line failed to execute:

Code:

---

"c:\myapp\regasm.exe" "C:\myapp\CameraController.dll" /tlb:"C:\myapp\CameraController.tlb" /codebase

---

It has raised the following error:

Code:

---

Microsoft (R) .NET Framework Assembly Registration Utility 4.0.30319.1
Copyright (C) Microsoft Corporation 1998-2004.  All rights reserved.

RegAsm : error RA0000 : An error occurred while writing the registration
information to the registry. Administrator permissions are needed to use the
selected options. Use an administrator command prompt to complete these
tasks."

This command line works perfectly on Windows XP. I must mention that I want to register this component from a bat file and I have no clue what I'm doing wrong. I even tried to use "runas", but it's asking me for the password whole the time however system doesn't have any password set.

Has anybody any idea how to register one COM interop dll on Windows 7 systems from the batch file?
Any help, input, hint is highly appreciated.

Thank you in advance!

Not sure, but have you checked if UAC is enabled ?

UAC was initially enabled but I turned off. I getting the same message from regasm in command prompt window. When I run command prompt as administrator then works! But how to execute regasm as administrator from one .bat file? I cannot expect from simple users to do these steps. Maybe "runas" is a solution, but it asks me for a password when I want to start cmd as administrator however system doesn't have any password. In XP everything is fine, but Win7 is very frustrating sometimes. :-/
Any workaround?

Are the users local administrators?

There is only one user: Developer (without any password) and he is the system administrator.

This seems to be what you're after.

Don't have time to test it myself, but it's just a suggestion.

Hi folks!
Seems to be I solved the problem. I would like to share my experience.
Here it is what I did to using "regasm.exe" register a COM interop dll written in VB.NET 2010:

1) First of all, I had to turn off UAC. I did it from the script of course, because I cannot expect from end-user to start "msconfig" and play with the settings.

I simply modified the values in the registry:
In "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System" there are two important settings for this case: "EnableLUA" and "ConsentPromptBehaviorAdmin". They have value different then zero by default. These values I set to 0.

2) Restart the system (I forgot to do that, this was the reason why "regasm" didn't work)

3) Start installation again from registry's "Run Once"

4) Install the interop dll with all dependencies

5) Register dll and export tlb using regasm.exe:

"c:\myapp\regasm.exe" "C:\myapp\CameraController.dll" /tlb:"C:\myapp\CameraController.tlb" /codebase

6) Set values back to "EnableLUA" and "ConsentPromptBehaviorAdmin" (that OPTIONAL, but I did)

7) Restart the system once again (only in case of 6))

That's all. Everything works fine!

Thank you for helping me and giving suggestions!

Have a nice weekend!
