Syncfusion Licensing Runtime

[Dorian]

Hi, I'm having the following issue: 

I need to make some changes in an application, that was created many years ago, but I don't have the source code (the person who create it don't work in the company anymore and we don't have the source code), so I have to use JetBrains DotPeek to decompile and recreate the code. But I don't know how to obtain the license key, and I don't know if I have to install Syncfusion in my development machine. The version of the Syncfusion.Core dll is 4.402.0.51. Can anyone help me. Thanks.

Hi Dorian,

Essential Studio Setup v4.4.0.51 should be installed to use the Syncfusion.Core.dll. 

 

Please download the Syncfusion installer from the below link.

 

https://www.syncfusion.com/account/downloads/studio/licensed/4_4_0_51

After downloading the setup, generate an unlock key to unlock the 4.4.0.51 setup. Please refer to the below KB to know more about an unlock key.

 

https://www.syncfusion.com/kb/9568/how-to-use-the-unlock-key-in-syncfusion-installer

 

Please ensure the below registry keys present in your machine after installing the setup, 

 

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Syncfusion\Essential Suite\InstalledVersions 

 

Ensure Your unlock key is registered in the registry key below. 

 

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Syncfusion\Essential Suite\InstalledVersions\Keys 

 

 

 

 

Could you please follow the steps provided in the documentation link to resolve the reported licensing issue in v4.5.0.51 version?

Thanks Jeyaseelan!! that fix the Licensing error. Now I have this other error: 

System.TypeInitializationException: 'The type initializer for 'Syncfusion.Windows.Forms.Tools.XPMenus.BarManager' threw an exception.'

Do you know how I can solve this. Many thanks.
