After a timeout of a message sent from the XenApp server to the License Server occurs, subsequent communication to the License Server does not occur correctly because the persistent connection from XenApp to the License Server becomes unstable.

When I try to create a windows store program in Visual Studio 2012, I was prompt to install the developer license, but VS2012 failed to get the license all the time, please see the picture below.

I closed this dialog and try it againd from Project-Store-Acquire Developer License, but still get the same error. I google this for a while and found a page on MSDN said there is a command mode, I try that, get the same error, see below picture.

I upgrade my Windows 8 from Windows 7 several days ago, and it was actived.

I didn't use any proxy for my internet connection, I can not build my windows store prgram without the license. any work around for this?

Run Command Prompt as administrator. If you are prompted for an administrator password or confirmation, type the password or provide confirmation. Type netsh winhttp reset proxy at the command prompt, and press Enter. Try to get licence again.

I had a similar problem. I have just installed Windows updates and now everything is working.

1. Open the “Edit Group Policy” Management Editor
2. Click to expand Computer Configuration, Administrative Templates, Windows Components, and then App Package Deployment.
3. Double-click the Allow development of Windows Store apps without installing a developer license setting.
4. In the Allow development of Windows Store apps without installing a developer license window, click Enabled and then click OK.
5. Double-click the Allow all trusted apps to install setting.
6. In the Allow all trusted apps to install window, click Enabled and then click OK. Setting the Group Policy to allow development of Windows Store apps without installing a developer license updates the following registry setting: HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftWindowsAppxAllowDevelopmentWithoutDevLicense = 1 Setting the Group Policy to allow trusted applications updates the following registry setting: HKEY_LOCAL_MACHINESoftwarePoliciesMicros oftWindowsAppxAllowAllTrustedApps = 1

If you are still facing same problem Then follow below steps: 1. Open following link and download Hotfixhttp://support.microsoft.com/kb/2871280 2. Install Hotfix and restart machine.

Another alternative: • Start the Fiddler on the system and then try to get the Window Developer License

The problem is due to Task Scheduler corruption during the upgrade processA hotfix was published by Microsoft, which resolves the issue: http://support.microsoft.com/kb/2687198

If applying the hotfix does not work, try the following:

1. Create a new temporary user.
2. Switch to the new temporary user. (Go to Start screen, click on your name/avatar, click on new username in drop down box, and enter password.)
3. As the new user, open Visual Studio 11.
4. Create a new Metro project. When asked to acquire a new license, log in with your Microsoft Account.
5. Log off and switch back to my normal user account.
6. Open Visual Studio and your try running your Metro project.
7. Disable the temporary user. (it might be needed again when the license expires.)

I had the same problem and nothing I found on the web would help. The nice guy at MSDN Developer Hotline pointed out to me, that the system date and time must be set to the correct local time. That finally solved the problem and I was now able to activate a developer license.

If I understood him right, this is due to some SSL connection that failes if the time settings on both participants differ too much.

None of the above works, I refresh my Windows 8 again. it works now.
