AppBuilder crashing

[Scott]

I'm having a problem with AppBuilder, as soon as I launch it it crashes.  When I look in the logs I see the following stack trace.

Hi Scott,

Thanks for the provided stack trace.
The first thing I noticed is a bit old version you are using. The current one is Version 2014.3.1218.1 so I guess this might be the cause for your issue.
That is why I would ask you to uninstall your AppBuilder from Windows control panel. Then use this link to download AppBuilder (I suppose you are using Windows client) and install it.

If this does not help please send us the latest log from  %localappdata%\Telerik\BlackDragon\Logs folder produced using our latest client version in a private support ticket.

I look forward to your reply.

Okay uninstalling and re-installing does the trick.  I was trying to re-install a newer version over the old and that didn't seem to work.

Hi Scott,

Usually our client should get automatically updated when started and a newer version is available.
The most important is that everything is back to normal and you can continue your development.

If you have any other issues do not hesitate to contact us.
