Different Lead versions in the same computer

I have Lead Document Imaging v14.0 installed in my computer and I downloaded the evaluation version 14.5 but now my old application using  the licensed version is pointing to the objects in the evaluation version.

Is there a way to avoid this, and have both version installed in the same computer?

Thanks

 

For LEADTOOLS ActiveX and COM objects, the Evaluation and Release versions have the same class IDs and programming interfaces. This means registering one of them will cause it to replace the other.

This should not cause any problems in you case. You can simply use the free evaluation edition, even in your old application. When you finish evaluation, uninstall the EVAL and re-register all the Release objects.

I just uninstall the evaluation version, register the ocx again, and re-compile my programs, but some users are getting the internal error 20900. The error says:

OLE IDispatch exception code 0 from LTOCX14N: LEAD Error: Internal Error 20900 - call LEAD..

Could you help me to fix it?

Thank you

Melva,
This error is ERROR_LTCLR_DLL_NOTLOADED "The LTCLR DLL is not loaded".
Some functions need the file LTCLR14N.DLL for color conversion and image display, so you should distribute it if your program uses any of these functions.
