 Posted: Tue Jun 11, 2013 10:41 am Post subject: Cryptographic Exception |
 |
|
Hello,
I have a customer's application where a CryptographicException is thrown when the AuthenticatedLicenseProvider constructor is called.
The exception message is "The profile for the user is a temporary profile".
Is it a known behavior ?
I know that a temporary profile is created when the user's profile can not be loaded, and so it is considered as an error, but apart from correcting it, is there any workaround ?
Thans in advance |

What sort of application are you licensing (Windows Forms, WPF, Windows Service or ASP.NET)?
When is the licensing code being called (at installation, normal execution)?

This is a Winform Application built on top of .Net 2.0 with your Licensing System 5.5.3 (modified source code). The computer is running XP SP3
I've managed to add some try catch around the application initialization (when I want to check if the user has a license file so he can use the full application), and this is the exception I get :
| Code: |
Exception : The type initializer for 'MyApp.LocalLicenseServer' threw an exception.

I think that this may be related to an issue that was fixed in Version 5.7.0 of ILS. I suggest you download the latest ILS code (using the original download link you received when you purchased) and use it.

I've upgraded my application with ILS 5.10.2 and can confirm that the previous cryptographic exceptions are now gone.
Thanks |
