The usual cause of this error is that your system cannot locate the current version of a component or the license for the component has been removed. Try the following steps:

1. Close all relevant applications that use the component such as Visual Studio, Excel, Access, Delphi.
2. Ensure that you have removed any old versions of the software. Remove the current version of the software.
3. Re-install the current version of the software.
4. Open up the form in your VB project and remove the icon for the component you are using.
5. Save the project, close the project and reopen it.
6. Ensuring that you reference the correct, newest version of the component, place a new instance of the component icon on the form, and rename it to the correct name you use within the application.
7. Recompile the application and then try running it.

Provided the software has been installed correctly, this should solve the problem. If problems still persist, go back to Step 2, except that this time, after Step 2, do a search and remove any old DLL files that are from the software, eg the filename may be of the form "wttransformx.dll" and will generally be located in the Windows System32 directory. Continue with Step 3.

If you are still having problems, ensure that the problem is related to our components. Try starting a brand new project and see if you can create and compile a simple project which does nothing.
