Invalid license error with purchased Multimedia 14.5 SDK

Hello,

I have recently purchased the LeadTools Multimedia SDK 14.5. When I was testing the release on my dev machine I am getting the following error:

'You do not have a license to use ths ActiveX control.'

I am quite confused because the evaluation version of the Multimedia SDK worked fine. These are the steps that I did:

- unregistered and deleted LTMM_E.dll from C:\WINNT\SYSTEM32 folder
- copied and registered LTMM_N.dll in the C:\WINNT\SYSTEM32 folder

Please help.

Thanks,
David

David,
Unlike the Evaluation edition, the Release (purchased) edition of our controls is licensed. This means you cannot use them in design mode on any machine other than the development machine.

On deployment machines, you can only use them in run mode. If you are creating the control programmatically or dynamically, you need to use the license string in the create statement. How exactly does your program create our multimedia control?

Thank you for your response.

The multimedia controls work fine in design mode on my development machine. I should have stated more clearly that it does not work on my test machine.  When I tested the evaluation version on the test machine the program worked.  However, when I tried to use the purchased version it started to give the error. The test machine now only contains the redistributable dll file (LTMM_N.DLL).

I have attached my code that uses the multimedia controls.

But I wonder if the following line will give me problems?
      
ltmmCaptureCtrl1.VideoCompressors.Selection = ltmmCaptureCtrl1.VideoCompressors.Find("@device:sw:{33D9A760-90C8-11D0-BD43-00A0C911CE86}\LEAD H.263 Encoder")

Thanks for your help.

Problem fixed!

I had the controls on their that were loaded from the evaluation version.  I had to load them again from the purchased version on my design.
