Activating volume licence Windows 8 from the GUI

Earlier I posted about the command line tricks required to activate Windows 8 installed from a volume licence media, because it seemed that the Change product key window is missing from the new OS (this was the case of the Activation Error: Code 0x8007232b. DNS Name does not exist – just for the search engines).

Well, the window is there, but you need a new way to display it. Here is the magic word you can enter into a Run dialog:

Yes, seriously:


And here comes the well-known Enter product key to activate Windows dialog:


Could someone bring back the button to the Computer properties window, please?



Visual Studio 2012 setup fails: The cabinet file is corrupt

A faced with a strange issue while installing Visual Studio 2012 RTM. I used this new feature of Windows 8 and mounted the setup ISO directly with Windows Explorer:


The installer seemed to work fine, but finally it failed installing the Core Components. I found the following in the setup log:

ExecuteError: Package (vs_professionalcore) failed: Error Message Id: 1335

ErrorMessage: Error 1335.The cabinet file ‘’ required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package.

So I sighed and went back to the old method, and used Daemon Tools to mount the ISO image, and the installer could complete successfully.

I opened a Connect bug for this issue, so if you encounter the same problem, you can vote for it here:

Visual Studio 2012, the disk eater

Visual Studio was never a small software, it always required a bunch of disk space. This statement is especially true since the release of Visual Studio.NET (if you remember, that was the 2001 version for .NET 1.0), which combined several programming languages and you no longer had to install different IDEs for C++ and Visual Basic. But since then the setup provided options to install only those languages that you really use, for example I haven’t installed C++ and Visual Basic for years. The prerelease versions of Visual Studio 2012 didn’t provide such options, let’s see what happened with the RTM!

You will have your first Oh God moment in the first step, when you realize that the new Studio wants 8.48 GB from your disk. Besides that, everything looks OK:


That’s a LOT, especially in the world of SSDs. Like it or not, you have no other options here. You have to check the I agree checkbox to step forward:


In the next step you can relieve a bit, because fortunately here you can turn off some components. You will see the warning here, if you don’t have enough disk space:


If you turn off everything, you will still need 5.90 GB disk space for Visual Studio 2012 Ultimate:


Click on INSTALL to see the new progress bars:


That’s all, no language selection. I miss that not only because it eats my disk space, but also because I create too much Visual Basic and F# projects since I install VS 2012 Mosolygó arc

So, the good news is, that you have more customization options than you had in the prerelease version, the bad news is, that there aren’t as many as you expected for the RTM. I’m on several internal mailing lists, and it’s obvious that the setup team is not satisfied with this situation, and you will see further improvements in the future. Till then, if you want to motivate them, you can vote here for this issue:

Windows 8 VPN error 942

After installing Windows 8 RTM, I tried to setup a VPN connection as usual. On Windows 7 it was really trivial, it didn’t ask anything beside the VPN server address and the login credentials. However on Winodws 8 I got the following error message:

Error 942:

The connection could not be established because the authentication method used by your connection profile is not permitted for use by an access policy configured on the RAS/VPN server. Specifically, this could be due to configuration differences between the authentication method selected on the RAS/VPN server and the access policy configured for it.

You can find the problem on the Security tab of the VPN connection Properties window. By default none of the Authentication radio button are selected:


The solution: explicitly select an authentication method. Thank God, it doesn’t work without it Mosolygó arc

Windows 8 activation error: Code 0x8007232b

UPDATE: You can do that from the GUI too!

If you installed Windows 8 from a volume licence media, you will probably see the following error message when you try to activate Windows:

Activation Error: Code 0x8007232b
DNS Name does not exist

The solution, just like earlier with Windows Server 2008, is to enter a valid product key, that was not requested during installation.

Unfortunately, this new version of Windows does not provide the Change product key option in the Computer properties window, so you will need an elevated Command Prompt:


That’s all, now you can activate Windows without any error (hopefully).
