App Builder : Windows client crash since maintenance

[Jeelig]

Since yesterday (7th February), it's impossible to open a project within the windows client of Telerik Appbuilder.
The application launches correctly, but once I try to open an existing project it crashes and close.
Is there a chance that this is due to the planned maintenance operation?
Currently stuck on my work :'(

Hi Gilles,

I deeply sorry for your troubles, can you first verify that your projects are OK via the web client at https://platform.telerik.com?

Could you also send us the AppBuilder logs located at
 %localappdata%\Telerik\BlackDragon\Logs ?

Also can you please check if deleting the content inside the
 %localappdata%\Telerik\BlackDragon\Cache
and restarting the Windows Client, will solve your issues?

My first instinct was to verify the web client.
- The web client is OK, I can update and work on projects (but still need to update each time I need to check on mobile)
- I removed all files inAppData\Local\Telerik\BlackDragon\Cache and tried to launch the app (same behavior)
- Find attached some of the logs I have
PS: I changed the format from log to txt in order to join it

Hi Gilles,

If you are still having issues with the Windows client, would you please run Fiddler to capture the HTTP requests AppBuilder sends when you hit the Sign In button. If you send those over we might be able to find more information and further investigate the case.

Fiddler is a tool that will intercept the HTTP requests AppBuilder performs and give you the option to save them to disk. In order to capture the traffic with Fiddler follow these steps:
1.    Download Fiddler from here and install it.
2.    Run Fiddler and go to Tools -> Fiddler Options.
3.    On the HTTPS page, verify that Capture HTTPS Connects is enabled.
4.    Verify that Decrypt HTTPS traffic is enabled with the ...from all processes option and minimize Fiddler to tray.
5.    Run your AppBuilder client and try to open a project
6.    In Fiddler, go to File -> Save -> All Sessions, save the archive to disk. This will produce a SAZ file.
7.    Zip the .saz file and send it over in a ticket 

Then you can try performing a complete unnstallation of the AppBuilder windows client following the steps outlined here. Then you should be able to install it again and work within your Telerik Platform account as expected.

I'd love a follow up on this if there is any new information.  I'm having the exact same issue.

Hello Kyle,

I am sorry to see you are experiencing issues with the Windows client. Am I right to assume they appeared after you updated the client to the latest release. If so, the issue might be coming from an incomplete or incorrect update. It might therefore help to reinstall the client following these steps:

1. Close all running instances of the AppBuilder Windows client.
2. Run the Windows Task Manager.
3. From the Processes tab, make sure there are no  Icenium.Graphite.exe processes and close the Task Manager.
4. Run your default uninstall tool. For example, the Windows Uninstall or change a program tool.
5. In Windows Explorer, go to %LOCALAPPDATA%\Telerik and delete the BlackDragon folder, if present.
6. In Windows Explorer, go to %LOCALAPPDATA%\Apps\2.0 and delete its contents. This operation will remove data for ClickOnce applications on your system.
7. Download AppBuilder and install it again

Also, in order to investigate the case we would need more information. Can you gather the following logs before uninstalling the Windows client:

• The logs available under the %localappdata%\Telerik\BlackDragon\Logs folder
• Open Event Viewer by clicking the Start button, clicking Control Panel, clicking System and Security, clicking Administrative Tools, and then double-clicking Event Viewer.‌ 
• Click the Windows logs in the left pane.
• Look for errors coming from AppBuilder and if there are any, please double click the error and send over the details.
• Any additional details you can provide about when and how the client crashes

Let me know whether the reinstallation helps.

Hi,

Thank you for the help.  I've done a complete uninstall including deleting the BlackDragon folder and the contents the of the Apps/2.0 folder.  I'm still encountering the same crash error.  It works as described above.  I can open the Windows client ok, and I can see my dashboard.  However, when I try to open a project the AppBuilder tool crashes.

Here is the text from the log:
[2015-02-16 13:13:48.018] Log (Exception,High): System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task System.Threading.Tasks.Task`1.ContinueWith(System.Action`2<System.Threading.Tasks.Task`1<!0>,System.Object>, System.Object)'.

I am not seeing anything in my Event Viewer related to AppBuilder either.  And yes, this morning is the first time i've seen this issue.  AppBuilder updated this morning and i've had an issue ever since.

Hello Kyle,

I haven't seen this exception before and I will need more time investigate the case further. In the meantime, can you also capture the HTTP requests using Fiddler and send them over. The procedure is described in this thread.

In the meantime can you try using some of the other AppBuilder clients - for instance the In-browser client. You should be able to successfully open and work on your projects with it.

Hello Kyle,

We were able to replicate the issue locally and the cause is in the .NET 4.0 version running in the Windows machine. I suppose your machine is also running .Net 4.0. If this is indeed the case, then the issue will be resolved with the upcoming hotfix we will release by the end of the week.

In the meantime I was wondering is there any chance you can update your .NET installation to 4.5. AppBuilder will not be able to run at all on .NET 4.0 in a couple of releases and in case you cannot update the .NET version on your machine, I will appreciate it if you can let us know why. It would help us to know what might be preventing customers from upgrading the .NET runtime on their machine.

Hi Tina,

The update to .NET 4.5 did the trick!   Thank you for the prompt help and keeping me updated.

Tina,

I am currently running Windows XP on my development machine, and am unable to upgrade to .Net 4.5...

[Tina Stancheva]

Hello Paul,

I just saw your post here, which means that the .Net framework version is indeed the cause for the issue on your side as well. Since you cannot currently update its version and there isn't a workaround for the issue, I want to ask you to try using some of the other AppBuilder clients until the hotfix comes out later in the week.

You should be able to open your projects from Chrome using the Telerik In-Browser client (by logging in platform.telerik.com) since the Windows and the In-Browser client share the same repository thus allowing you to work on the projects from different devices or environments. You can also try the AppBuilder VisualStudio client or the Command-Line interface. In that case, however, you would have to go through the In-Browser client to export your project.

I am very sorry for the inconvenience this issue has introduced and the delay it might be causing in your development process. We are doing our best to address it as soon as possible and release a hotfix with the update.

Tina Stancheva

Hello guys,

As a follow-up I just want to let you know that we released a hotfix addressing the .Net 4.0 issue. The AppBuilder Windows client will alert you to update as soon as you open it and you should be able to open your projects even if you don't have .Net 4.5 on your machine.
