VB4: Compiling Problems/errors

We have our project developed in Visual Basic 4.0. Now, we are in the process of upgrading the product with new features. However, when we run the project, we get ERRORS like:
1) Cannot load the .VBX file
&
2) License file for the custom Control not available.

Any help will be appreciated. Thanks.

VBX controls are 16bit. If you are trying to develop them in a 32bit environment (and itf you aren't you should be) you need to find OCX 32bit versions of the controls. Good news is that chances are that they are available unless your using a really old 3rd part control that is no longer produced.
