Hi Joel,
Sorry for the inconvenience caused.
I feel that your GAC has also got the older versions assemblies installed in it.
Could you please follow these steps:1. Please open 6.3.x.x Assembly Manager from dashboard and choose option remove all versions and click Perform action.
2. Please check whether all the syncfusion assemblies are removed from the below locations.
C:\WINDOWS\assembly
C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PublicAssemblies
C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5
C:\Program Files\Common Files\Microsoft Shared\MSEnv\PublicAssemblies
3. Again from the assembly manager choose install version to install the version 6.3.x.x assemblies.
4. Make sure that your machine contains only the 6.3.x.x assemblies in the above given locations.
5. Please run the utility manager which i attached to you in my previous update.
6. While running the utility manager please choose 2.0 framework and click ok once succesfully completed.
7. Open your application and make sure in the properties window whether you references points to version 6.302.X.X
8. Set specific version property to false in the properties window.
9. Compile and run the project.
If you still have problem, please refer this KB link
